Answer:

x = 2

Step-by-step explanation:

Step 1: Write equation

5x - 1 = 7 + x

Step 2: Solve for x

  1. Subtract x on both sides: 4x - 1 = 7
  2. Add 1 to both sides: 4x = 8
  3. Divide by 4 on both sides: x = 2

Step 3: Check

Plug in x to verify it's a solution.

5(2) - 1 = 7 + 2

10 - 1 = 9

9 = 9
