6-12x+3\left(2x-5\right)=4\left(3x+1\right)-2\left(3x-1\right)
Use the distributive property to multiply 3 by 2-4x.
6-12x+6x-15=4\left(3x+1\right)-2\left(3x-1\right)
Use the distributive property to multiply 3 by 2x-5.
6-6x-15=4\left(3x+1\right)-2\left(3x-1\right)
Combine -12x and 6x to get -6x.
-9-6x=4\left(3x+1\right)-2\left(3x-1\right)
Subtract 15 from 6 to get -9.
-9-6x=12x+4-2\left(3x-1\right)
Use the distributive property to multiply 4 by 3x+1.
-9-6x=12x+4-6x+2
Use the distributive property to multiply -2 by 3x-1.
-9-6x=6x+4+2
Combine 12x and -6x to get 6x.
-9-6x=6x+6
Add 4 and 2 to get 6.
-9-6x-6x=6
Subtract 6x from both sides.
-9-12x=6
Combine -6x and -6x to get -12x.
-12x=6+9
Add 9 to both sides.
-12x=15
Add 6 and 9 to get 15.
x=\frac{15}{-12}
Divide both sides by -12.
x=-\frac{5}{4}
Reduce the fraction \frac{15}{-12} to lowest terms by extracting and canceling out 3.
