3\left(3x-6\right)-6\left(x+5\right)=2\left(x-4\right)
Multiply both sides of the equation by 12, the least common multiple of 4,2,6.
9x-18-6\left(x+5\right)=2\left(x-4\right)
Use the distributive property to multiply 3 by 3x-6.
9x-18-6x-30=2\left(x-4\right)
Use the distributive property to multiply -6 by x+5.
3x-18-30=2\left(x-4\right)
Combine 9x and -6x to get 3x.
3x-48=2\left(x-4\right)
Subtract 30 from -18 to get -48.
3x-48=2x-8
Use the distributive property to multiply 2 by x-4.
3x-48-2x=-8
Subtract 2x from both sides.
x-48=-8
Combine 3x and -2x to get x.
x=-8+48
Add 48 to both sides.
x=40
Add -8 and 48 to get 40.
