Answer:

x=12

Step-by-step explanation:

3(x-1)=2x+9       - Original equation

3x-3=2x+9        - Distribute 3 through the parentheses

3x-2x-3=9         - Move variable to the left-hand side and change sign

3x-2x=9+3        - Move constant to the right-hand side and change its sign

x=9+3               - Collect like terms and add

x=12                  - Answer
