simplify your answer as much as possible.
question 4 of 15
solve for u.
2u + 5 = 4u + 13
simplify your answer as much as possible.

Explanation:

Question 3 (Solve for $y$):

Step1: Combine like $y$ terms

$19 = -12y - 17$

Step2: Add 17 to both sides

$19 + 17 = -12y$
$36 = -12y$

Step3: Divide by -12

$y = \frac{36}{-12}$

Question 4 (Solve for $u$):

Step1: Subtract $2u$ from both sides

$5 = 2u + 13$

Step2: Subtract 13 from both sides

$5 - 13 = 2u$
$-8 = 2u$

Step3: Divide by 2

$u = \frac{-8}{2}$

Answer:

$y = -3$
$u = -4$
