Question

solve for u.
3(u - 5) = 9u + 45
simplify your answer as much as possible.

u =

Explanation:

Step1: Expand left-hand side

$3u - 15 = 9u + 45$

Step2: Move u terms to one side

$3u - 9u = 45 + 15$

Step3: Simplify both sides

$-6u = 60$

Step4: Solve for u

$u = \frac{60}{-6} = -10$

Answer:

$u = -10$
