4\left(x-2\right)-2\left(2x+1\right)=3\left(3x-1\right)-6\left(2x+1\right)
Multiply both sides of the equation by 12, the least common multiple of 3,6,4,2.
4x-8-2\left(2x+1\right)=3\left(3x-1\right)-6\left(2x+1\right)
Use the distributive property to multiply 4 by x-2.
4x-8-4x-2=3\left(3x-1\right)-6\left(2x+1\right)
Use the distributive property to multiply -2 by 2x+1.
-8-2=3\left(3x-1\right)-6\left(2x+1\right)
Combine 4x and -4x to get 0.
-10=3\left(3x-1\right)-6\left(2x+1\right)
Subtract 2 from -8 to get -10.
-10=9x-3-6\left(2x+1\right)
Use the distributive property to multiply 3 by 3x-1.
-10=9x-3-12x-6
Use the distributive property to multiply -6 by 2x+1.
-10=-3x-3-6
Combine 9x and -12x to get -3x.
-10=-3x-9
Subtract 6 from -3 to get -9.
-3x-9=-10
Swap sides so that all variable terms are on the left hand side.
-3x=-10+9
Add 9 to both sides.
-3x=-1
Add -10 and 9 to get -1.
x=\frac{-1}{-3}
Divide both sides by -3.
x=\frac{1}{3}
Fraction \frac{-1}{-3} can be simplified to \frac{1}{3} by removing the negative sign from both the numerator and the denominator.
