solve for u.\n-9 - 4u = -u\nu = \nsubmit
solve for u.\n-9 - 4u = -u\nu = \nsubmit
Answer
Explanation:
Step1: Add 4u to both sides
$-9 - 4u+4u=-u + 4u$ $-9 = 3u$
Step2: Divide both sides by 3
$\frac{-9}{3}=\frac{3u}{3}$
Answer:
$-3$
solve for u.\n-9 - 4u = -u\nu = \nsubmit
$-9 - 4u+4u=-u + 4u$ $-9 = 3u$
$\frac{-9}{3}=\frac{3u}{3}$
$-3$
