    8 (v-4) + 7v=-2

    (8) (v) + (8) (-4) + 7v=-2

    8v+-32+7v=-2

    (8v+7v) + (-32) = - 2

    15v+-32=-2

    15v-32=-2

    Add 32 to both sides.

    15v-32+32=-2+32

    15v=30

    Divide both sides by 15.

    15v/15=30/15

    v = 2

    8 (v-4) + 7v = - 2 Original Problem.

    8v - 32 + 7v = - 2 Distribute.

    8v + 7v = 30 Add 32 to each side.

    15v = 30 Add.

    v = 2 Divide each side by 15.

    Answer: v = 2
