2(v+7)=-16+7v

We move all terms to the left:

2(v+7)-(-16+7v)=0

We add all the numbers together, and all the variables

2(v+7)-(7v-16)=0

We multiply parentheses

2v-(7v-16)+14=0

We get rid of parentheses

2v-7v+16+14=0

We add all the numbers together, and all the variables

-5v+30=0

We move all terms containing v to the left, all other terms to the right

-5v=-30

v=-30/-5

v=+6
