Answer:

x = 21

Step-by-step explanation:

Step 1: Write equation

3(x - 1) = 2(x + 9)

Step 2: Solve for x

  1. Distribute: 3x - 3 = 2x + 18
  2. Subtract 2x on both sides: x - 3 = 18
  3. Add 3 to both sides: x = 21

Step 3: Check

Plug in x to verify it's a solution.

3(21 - 1) = 2(21 + 9)

3(20) = 2(30)

60 = 60
