Question

solve for u. 3(u + 4) = -6u + 48 simplify your answer as much as possible.

Explanation:

Step1: Expand left-hand side

$3u + 12 = -6u + 48$

Step2: Add $6u$ to both sides

$3u + 6u + 12 = 48$
$9u + 12 = 48$

Step3: Subtract 12 from both sides

$9u = 48 - 12$
$9u = 36$

Step4: Divide by 9

$u = \frac{36}{9}$

Answer:

$u = 4$
