3\left(2x+1\right)+2\left(2x-1\right)=6\left(2x-1\right)-12x-12+4x
Multiply both sides of the equation by 12, the least common multiple of 4,6,2,3.
6x+3+2\left(2x-1\right)=6\left(2x-1\right)-12x-12+4x
Use the distributive property to multiply 3 by 2x+1.
6x+3+4x-2=6\left(2x-1\right)-12x-12+4x
Use the distributive property to multiply 2 by 2x-1.
10x+3-2=6\left(2x-1\right)-12x-12+4x
Combine 6x and 4x to get 10x.
10x+1=6\left(2x-1\right)-12x-12+4x
Subtract 2 from 3 to get 1.
10x+1=12x-6-12x-12+4x
Use the distributive property to multiply 6 by 2x-1.
10x+1=-6-12+4x
Combine 12x and -12x to get 0.
10x+1=-18+4x
Subtract 12 from -6 to get -18.
10x+1-4x=-18
Subtract 4x from both sides.
6x+1=-18
Combine 10x and -4x to get 6x.
6x=-18-1
Subtract 1 from both sides.
6x=-19
Subtract 1 from -18 to get -19.
x=\frac{-19}{6}
Divide both sides by 6.
x=-\frac{19}{6}
Fraction \frac{-19}{6} can be rewritten as -\frac{19}{6} by extracting the negative sign.
