    Answer:

    1) x = 11

    2) x = ½

    Step-by-step explanation:

    1) 2(x – 5) + 7 = x + 8

    2x – 10 + 7 = x + 8

    2x – 3 = x + 8

    x = 11

    2) 5(x – 1) – 6x = -11x

    5x – 5 – 6x = -11x

    -5 – x = -11x

    10x = 5

    x = ½

    Answer:

    x = 11

    1/2 =x

    Step-by-step explanation:

    1) 2(x – 5) + 7 = x + 8

    Distribute

    2x-10+7 = x+8

    Combine like terms

    2x -3 = x+8

    Subtract x from each side

    2x-x-3 = x+8-8

    x -3 = 8

    Add 3 to each side

    x-3+3 = 8+3

    x = 11

    2) 5(x – 1) – 6x = -11x

    Distribute

    5x-5-6x = -11x

    Combine like terms

    -x-5 = -11

    Add x to each side

    -x+x -5 = -11x +x

    -5 = -10x

    Divide each side by -10

    -5/-10 = -10x/-10

    1/2 =x
