Answer:
x = 21
Step-by-step explanation:
Step 1: Write equation
3(x - 1) = 2(x + 9)
Step 2: Solve for x
- Distribute: 3x - 3 = 2x + 18
- Subtract 2x on both sides: x - 3 = 18
- 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
