2\times 2\left(x-1\right)-3\left(2x+2\right)=6x-60
Multiply both sides of the equation by 6, the least common multiple of 3,2.
4\left(x-1\right)-3\left(2x+2\right)=6x-60
Multiply 2 and 2 to get 4.
4x-4-3\left(2x+2\right)=6x-60
Use the distributive property to multiply 4 by x-1.
4x-4-6x-6=6x-60
Use the distributive property to multiply -3 by 2x+2.
-2x-4-6=6x-60
Combine 4x and -6x to get -2x.
-2x-10=6x-60
Subtract 6 from -4 to get -10.
-2x-10-6x=-60
Subtract 6x from both sides.
-8x-10=-60
Combine -2x and -6x to get -8x.
-8x=-60+10
Add 10 to both sides.
-8x=-50
Add -60 and 10 to get -50.
x=\frac{-50}{-8}
Divide both sides by -8.
x=\frac{25}{4}
Reduce the fraction \frac{-50}{-8} to lowest terms by extracting and canceling out -2.
