Question

solve for $u$.
$-53 = 8u + 4u - 17$
simplify your answer as much as possible.
$u = \square$

Explanation:

Step1: Combine like terms

$8u + 4u = 12u$, so the equation becomes:
$-53 = 12u - 17$

Step2: Isolate the term with $u$

Add 17 to both sides:
$-53 + 17 = 12u$
$-36 = 12u$

Step3: Solve for $u$

Divide both sides by 12:
$u = \frac{-36}{12}$

Answer:

$u = -3$
