3\left(x+3\right)+4\left(2x+1\right)=2\left(x-3\right)+3x+1
Multiply both sides of the equation by 12, the least common multiple of 4,3,6,12.
3x+9+4\left(2x+1\right)=2\left(x-3\right)+3x+1
Use the distributive property to multiply 3 by x+3.
3x+9+8x+4=2\left(x-3\right)+3x+1
Use the distributive property to multiply 4 by 2x+1.
11x+9+4=2\left(x-3\right)+3x+1
Combine 3x and 8x to get 11x.
11x+13=2\left(x-3\right)+3x+1
Add 9 and 4 to get 13.
11x+13=2x-6+3x+1
Use the distributive property to multiply 2 by x-3.
11x+13=5x-6+1
Combine 2x and 3x to get 5x.
11x+13=5x-5
Add -6 and 1 to get -5.
11x+13-5x=-5
Subtract 5x from both sides.
6x+13=-5
Combine 11x and -5x to get 6x.
6x=-5-13
Subtract 13 from both sides.
6x=-18
Subtract 13 from -5 to get -18.
x=\frac{-18}{6}
Divide both sides by 6.
x=-3
Divide -18 by 6 to get -3.
