  1. First clear the parenthesis:

    13x+18=5-7+7x

    Group the terms:

    13x-7x=5-7-18

    6x=5-25

    6x=-20

    x=-20/6=10/3=3 1/3


  2. 13x + 18 = 5 - 7 + 7x

    13x - 7x = 5 - 7 - 18

    6x = -20

    x = -20 /6

    x = - 10 / 3

  3. 13x + 18 = 5 - 7(1-x)

    13x + 18 = 5 -7 +  7x

    13x + 18 = 7x - 2

    6x + 18 = -2

    6x = -20

    x = -20/6

    x = -10/3

  4. 13x+18=5-7(1-x)

    multiply 7 to "()"

    13x+18=5-7+7x

    subtract 7 from 5

    13x+18=-2+7x

    subtract 7x from both sides

    6x+18=-2

    subtract 18 from both sides

    6x=-20

    divide 6 from both sides

    x=3.3333333........

    that is your answer
