  1. 4.

    3 ( 4 - 2 x ) = - 2 x

    3 * 4 - 3 * 2 x = - 2 x

    12 - 6 x = - 2 x Add 6 x to both sides

    12 - 6 x + 6 x = - 2 x + 6 x

    12 = 4 x Divide both sides by 4

    3 = x

    x = 3

    Answer d

    5.

    5.4 + 0.2 x = - 1.4 x + 8.6 Subtract 5.4 to both sides

    5.4 - 5.4 + 0.2 x = - 1.4 x + 8.6 - 5.4

    0.2 x = - 1.4 x + 3.2 Subtract 3.2 to both sides

    0.2 x - 3.2 = - 1.4 x + 3.2 - 3.2

    0.2 x - 3.2 = - 1.4 x Subtract 0.2 x to both sides

    0.2 x - 0.2 x - 3.2 = - 1.4 x - 0.2 x

    - 3.2 = - 1.6 x Divide both sides by - 1.6

    - 3.2 / - 1.6 = x

    2 = x

    x = 2

    Answer a

    6.

    - 4 - 5 ( x + 8 ) =

    - 4 - 5 * x - 5 * 8 =

    - 4 - 5 x - 40 =

    - 5 x - 44

    Answer a

    7.

    3 x + 4 ( x - 6 ) - 3 ( x - 7 ) =

    3 x + 4 * x + 4 * ( - 6 ) - 3 * x - 3 * ( - 7 ) =

    3 x + 4 x - 24 - 3 x + 21 =

    4 x - 3
