  1. 5x - 6 = 7x

    step 1: subtract 5x from both sides
    step 2: which is -6 = 2x
    step 3: divide 2x from both sides
    step 4: x = -3
    step 5: put -3 in for x to check it

  2. 5x-6=7x
    1.subtract 5x from both sides
    2.you get -6=2x
    3.divide 2 from both sides
    4. you get x=-3

      first li8ke Kenneth said you subtract 5x from either side and then you get -6=2x then divide by two on each side and you get -3=xt

  3. 5x-6=7x
    First you subtract 5x from both sides and you get -6 = 2x.
    Second you divide 2 from both sides and you get x = -3

  4. The equation is 5x-6=7x. In order to solve this you first subtract 5x from both sides which is -6=2x. Then you divide 2 from both sides and you get x=-3. The number is -3.

  5. 5x-6=7x
    Subtract 5x.
    Divide by 2.
    x=-3

  6. first you set up an equation 5x-6=7x.
    then you would subtract 5x from both sides and get -6=2x.
    finally you would divide both sides by 2 and get -3=x.

  7. first you figure out how to write the equation which is 5x-6=7x. Then you would subtract 5x from both sides. last you would divide both sides by 2 and get -3.
    x=-3

  8. The equation that you would start off with is 5x-6=7x.
    -5x -5x
    -6=2x
    -3 =x

  9. I agree with all the people who said that the equation is 5x-6=7x, and that -3 is the number. This week in class, we learned how to add and subtract polynomials. We also learned how to multiply polynomials. A polynomial is a mononmial or sum of monomials.

  10. Forgot to say that each mononmial is called a term of the polynomial.

  11. Yes, agreed.
    5x-6=7x
    -5x -5x
    -6=2x -6/2=-3
    -3=x -Leah

    1. The First thing you do is set the equation up 5x-6=7x then you solve the equation ...
      5x-6=7x
      -5x -5x
      -6=2x -6/2=-3
      -3=x
