Question

solve for u.
-5u - 8 = -2u - 1 + 4u
u =
submit

Explanation:

Step1: Combine like terms on RHS

$-5u - 8 = (-2u + 4u) - 1$
$-5u - 8 = 2u - 1$

Step2: Move u terms to left side

$-5u - 2u - 8 = -1$
$-7u - 8 = -1$

Step3: Move constants to right side

$-7u = -1 + 8$
$-7u = 7$

Step4: Solve for u by dividing

$u = \frac{7}{-7}$

Answer:

$u = -1$
