Question

solve for u.
20 + 17u=-6 + 15u
simplify your answer as much as possible.

Explanation:

Step1: Move variable terms to one - side

Subtract $15u$ from both sides:
$20 + 17u-15u=-6 + 15u-15u$
$20 + 2u=-6$

Step2: Move constant terms to the other - side

Subtract 20 from both sides:
$20 + 2u-20=-6-20$
$2u=-26$

Step3: Solve for $u$

Divide both sides by 2:
$\frac{2u}{2}=\frac{-26}{2}$
$u = - 13$

Answer:

$u=-13$
