Solve for u

-8u + 6 (u+7) = 28

Simplify your answer as much as possible.

Answer: u=7

Step-by-step explanation:

First multiply 6 by u and 7 to get 6u+7

next add - 8u + 6u and get - 2u

then subtract 42 from both sides of the equation (28-42)

finally divide - 2u from both sides of the equation and get 7
