Answer:

u=36

Explanation:

1. multiply both sides by 4


( - 4 + u)/(4) * 4 = 8 * 4


- 4 + u = 32

2.now add 4 to both sides


- 4 + u + 4 = 32 + 4


u = 36

Answer:

u = 48

Explanation:

-4 + u/4 = 8

add 4 to both sides:

-4 + u/4 + 4 = 8 + 4

u/4 = 12

multiply both sides by 4:

4(u/4) = 4(12)

u = 48
