Question

solve for u.
2(u + 1) = 4u + 18
simplify your answer as much as possible.
u =

Explanation:

Step1: Expand left-hand side

$2(u+1) = 2u + 2$, so equation becomes $2u + 2 = 4u + 18$

Step2: Isolate u terms

Subtract $2u$ from both sides: $2 = 2u + 18$

Step3: Isolate constant terms

Subtract 18 from both sides: $2 - 18 = 2u$

Step4: Simplify and solve for u

$-16 = 2u$, so $u = \frac{-16}{2} = -8$

Answer:

$u = -8$
