2v+ 18 = 16 - 4(v + 7)
2v + 18 = 16 - 4v - 28
2v + 18 = - 12 - 4v
2v + 18 + 4v = - 12 - 4v + 4v
6v + 18 = - 12
6v + 18 - 18 = - 12 - 18
6v = - 30
6v / 6 = - 30 / 6
v = - 30/ 6
v = - 5

2v+18=16-4(v+7)
distribute
2v + 18 = 16 - 4v - 28
combine like terms
2v + 18 = -4v - 12
add 4v for both sides
6v + 18 = -12
subtract 18 for both sides
6v = -30
divide 6 for both sides
v = -5

2v+18=16-4(v+7)
2v+18=16-4v-28
2v+18=-4v-12
6v+18=-12
6v=-30
v=-5
Check:
2(-5)+18=16-4(-5+7)
-10+18=16-4(2)
-10+18=16-8
8=8
