Question

Answer 1

Answer:

x = -5

Step-by-step explanation:

-2x + 8 = 18

Subtract 8 from each side

-2x + 8-8 = 18-8

-2x = 10

Divide each side by -2

-2x/-2 = 10/-2

x = -5

Answer 2

Answer:

x = -5

Step-by-step explanation:

Step 1: Write equation

-2x + 8 = 18

Step 2: Solve for x

1. Subtract 8 on both sides: -2x = 10
2. Divide both sides by -2: x = -5

Step 3: Check

Plug in x to verify it's a solution.

-2(-5) + 8 = 18

10 + 8 = 18

18 = 18
