6\left(x+3\right)-3\left(3x+1\right)=4\left(2\left(x-2\right)-2\right)
Multiply both sides of the equation by 12, the least common multiple of 2,4,3.
6x+18-3\left(3x+1\right)=4\left(2\left(x-2\right)-2\right)
Use the distributive property to multiply 6 by x+3.
6x+18-9x-3=4\left(2\left(x-2\right)-2\right)
Use the distributive property to multiply -3 by 3x+1.
-3x+18-3=4\left(2\left(x-2\right)-2\right)
Combine 6x and -9x to get -3x.
-3x+15=4\left(2\left(x-2\right)-2\right)
Subtract 3 from 18 to get 15.
-3x+15=4\left(2x-4-2\right)
Use the distributive property to multiply 2 by x-2.
-3x+15=4\left(2x-6\right)
Subtract 2 from -4 to get -6.
-3x+15=8x-24
Use the distributive property to multiply 4 by 2x-6.
-3x+15-8x=-24
Subtract 8x from both sides.
-11x+15=-24
Combine -3x and -8x to get -11x.
-11x=-24-15
Subtract 15 from both sides.
-11x=-39
Subtract 15 from -24 to get -39.
x=\frac{-39}{-11}
Divide both sides by -11.
x=\frac{39}{11}
Fraction \frac{-39}{-11} can be simplified to \frac{39}{11} by removing the negative sign from both the numerator and the denominator.
