2\times 3\left(x+5\right)+12x-60=4\left(4x-1\right)-\left(2x-2\right)
Multiply both sides of the equation by 12, the least common multiple of 6,3,12.
6\left(x+5\right)+12x-60=4\left(4x-1\right)-\left(2x-2\right)
Multiply 2 and 3 to get 6.
6x+30+12x-60=4\left(4x-1\right)-\left(2x-2\right)
Use the distributive property to multiply 6 by x+5.
18x+30-60=4\left(4x-1\right)-\left(2x-2\right)
Combine 6x and 12x to get 18x.
18x-30=4\left(4x-1\right)-\left(2x-2\right)
Subtract 60 from 30 to get -30.
18x-30=16x-4-\left(2x-2\right)
Use the distributive property to multiply 4 by 4x-1.
18x-30=16x-4-2x-\left(-2\right)
To find the opposite of 2x-2, find the opposite of each term.
18x-30=16x-4-2x+2
The opposite of -2 is 2.
18x-30=14x-4+2
Combine 16x and -2x to get 14x.
18x-30=14x-2
Add -4 and 2 to get -2.
18x-30-14x=-2
Subtract 14x from both sides.
4x-30=-2
Combine 18x and -14x to get 4x.
4x=-2+30
Add 30 to both sides.
4x=28
Add -2 and 30 to get 28.
x=\frac{28}{4}
Divide both sides by 4.
x=7
Divide 28 by 4 to get 7.
