Answer:
x = 2
Explanation:
Step 1: Write equation
5x + 4 - 3x + 8 = 16
Step 2: Solve for x
Combine like terms: 2x + 12 = 16
Subtract 12 on both sides: 2x = 4
Divide both sides by 2: x = 2
Step 3: Check
Plug in x to verify it's a solution.
5(2) + 4 - 3(2) + 8 = 16
10 + 4 - 6 + 8 = 16
14 - 6 + 8 = 16
8 + 8 = 16
16 = 16
