Verified Answer :

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
