Due October 4, 2013

Create a two step equation.  You must solve the equation of the last post before yours.  The first person must solve this equation.  Use three sentences to explain the steps you took to solve the equation.

16 = 4x - 8

30 comments:

  1. 16=4x - 8
    +8 +8
    24=4x
    24 divided by 4= 6
    First you add 8 to 16 and 8 then the 8s cancel out and 8+16=24. Then divid 4 by 24 and it equals 6.

  2. First you got to add 8 onto 8 and 16. Then you get 24=4x. Then you divide 24 by 4 and also divide 4x by 4. Then your answer will be 6=x

  3. 1st You have to add 8 to both sides and that leaves 4x=24 Then you have to Divide both sides by 4 because the opposite of multiplication is division so that step solves the equation so the answer is x=6

  4. 16= 4x - 8
    +8 +8
    -------------
    24= 4x
    4 4
    ----------
    6= x
    First you add 8 to 16 and -8. Then you get 24= 4x, next you divide both sides by 4. Your final answer is 6= x!

  5. 16= 4x - 8
    +8=4x + 8
    24=4x
    4 =4
    6=x
    What you do is first add 8 to 16 and -8 to cancel it out.Next you divide 24 and 4x by 4 to get the x alone.Finally what you should get is 6=x.
    NEW PROBLEM
    26=6x + 2

  6. 26=6x + 2 In reply to Nikola Drobnjak's problem.

    1. Subtract 2 from numbers 2 & 26. You should be left with 24 = 6x.
    2. Then divide 6 from both numbers 24 & 6 so x can be by itself.
    The final answer is x = 4.

    My equation:

    18 = 7x - 10

  7. 18=7x-10- Mary's equation.
    1. Add 10 to 18 and -10. This would cancel out the -10 so you would be left with 28=7x.
    2. Divide both sides by 7. This would isolated the x by itself.
    The answer is 4=x

    New equation:
    49 = 20x - 11

    ReplyDelete
  8. 49=20x-11
    +11 +11
    20/60=20x/20
    3=x
    72=10x=10

  9. in the original problem first you must add 8 to the -8 to cancel it out. After doing that then you have to take the number you get from adding 8 to 16, which is 24, and divide it by 4.

    so X=6.

  10. 47=9x+16 you subtract 16 from both sides nd it equals 31=9x then divide 9 from each side nd x=3.4

    ReplyDelete
  11. 69=5x+9. Subtract 9 from both sides to get 69=5x then you divide 5 from both sides x=12

  12. Thanks for leaving me with a question.
    Ok, lets see....... how about I just do Mr Jackson's. Now I can begin after a half hour of confusion.
    So 16=4x-8
    +8 both sides
    24=4x
    ÷ both sides by 4
    x=6. (The answer.)
    Now as I create a problem for the next person.
    8y-6(y-9)= 86

    1. That isn't a two step equation. It's a multi-step one, but I'll solve it.
      8y - 6 (y-9) = 86
      Distribute -6 to the numbers inside the parentheses.
      The outcome is: 8y - 6y - 54 = 86
      Then, you simplify. Which means combining like terms. (8y - 6y)
      2y - 54 = 86
      Now, it is a two-step equation.
      You add 54 to both sides. -54 should be canceled out and 86 + 54 is 140.
      2y = 54
      Divide both sides by 2. The answer is 70.
      Next problem || 44 = 6x + 9

      Delete
  13. Okay 44=6x + 9
    -9 on both sides which turns out to 35=6x
    you divide 6 on both sides and get 5.8 so x=5.8
    the next problem is 50=3x+5

    1. Thanks David. 50=3x+5
      Subtract both sides from 5.
      50 - 5= 45 Divide both sides by 3
      45 divided by 3 is 15.
      x=15.
      My problem to you is 248= 28v+84

      Delete
  14. OK 50=3x+5 so what I did first was I subtracted 5 from both sides. 50-5=3x. Next I divided 3 from both sides and I got 15=x.

    60-(-5x+2)=72x+8

    1. First i ditrubuted the 60 To -5x And 2 So Now its -300x+120=72x+8 next i - 72x from both sides Now im left with -372x+120=8 then i subtract 120 from both sides and be left with -492x=8 then i devide both by -492 so im left with x=-0.016260163

      My Problem Is ..... 154(6x+7)=4x+5x

      Delete
  15. First you distribute -1 to -5x and 2. Then you combine like terms. then you subtract 58 from both sides. And finely you divide 77 from both sides and get x=-o.64. next problem -60=56x-22.

    ReplyDelete
    Replies
    1. You first add 22 on each side and you get -38=56x and you can't multiply or divide -38 with 56x so the answer is -38=56x.


      Next problem 34 = 14 + 4p

      Delete
  16. 34=14+4p
    -14= -14=
    20= 4p=
    20/4=5
    4/4 cancels out.
    so p=5! check: 14+4(5)=34
    basically i subtracted 14 from each side and got 20=4p.
    then i divided 20 by 4 and got five(5).
    the four(4) cancels out and p=5!
    next problem is 25 = 5x+0

    ReplyDelete
  17. 25=5x+0
    -0 -0
    25=5x
    25/5x=5
    5x/5x=x
    x=5
    i subtracted 0 from both sides and got 25=5x. then i divided 25 by 5x and got 5.then i divided 5x/5x=x. 5x5+0=25
    next problem 90=20x+10

    ReplyDelete
  18. ..... So 90=20x+10
    90-10=80 you subtract 10 from both side and you get 80
    80=20x
    20/20 then you divide both side by 20 and you
    cancel the 20 than you divide from the 80 and you get 4 so x=4.
    Next Problem 30=7x+1

    ReplyDelete
  19. 30=7x+1
    subtract 1 from 30 and 1.
    which equals 29=7x
    29 divided by 7 is 4.14
    so x= 4.14.

    next problem: 45=4x+8

    ReplyDelete
    Replies
    1. 45=4x+8 first subract 8 from both sides making the problem 37=4x .Then you divide 37 and 4x by 4. So the answer is x= 9.25

      next problem 15x+2=47

      Delete
  20. x=3. 1-subtract 2 from 47 this is 25.
    2-Divide 45 by 15.
    3-check your work.
    next!
    1200 x 100x = 11200

    1. Your Problem didn't make sense so imma do my own. 60=6n+8. So what you do first is you subtract 8 from 8 and 8 from 60. Then bring it down 52=6n. So divide 6 with 52 and 6 with 6n and your answer will be 8.6

      NEXT PROBLEM: 9y+4=55
