3\times 3x+2\times 2\left(x-3\right)=12
Multiply both sides of the equation by 12, the least common multiple of 4,6.
9x+2\times 2\left(x-3\right)=12
Multiply 3 and 3 to get 9.
9x+4\left(x-3\right)=12
Multiply 2 and 2 to get 4.
9x+4x-12=12
Use the distributive property to multiply 4 by x-3.
13x-12=12
Combine 9x and 4x to get 13x.
13x=12+12
Add 12 to both sides.
13x=24
Add 12 and 12 to get 24.
x=\frac{24}{13}
Divide both sides by 13.
