Question

Solve for u.
-4+2 u = -10
Simplify your answer as much as possible.

Answer 1

u = -3

Explanation:

Step 1: Write equation

-4 + 2u = -10

Step 2: Solve for u

Add 4 to both sides: 2u = -6

Divide both sides by 2: u = -3

Step 3: Check

Plug in x to verify if it's a solution.

-4 + 2(-3) = -10

-4 - 6 = -10

-10 = -10
