3x+6+2\left(2x-2\right)=3\left(5x+10\right)-6\left(x+4\right)
Multiply both sides of the equation by 12, the least common multiple of 12,6,4,2.
3x+6+4x-4=3\left(5x+10\right)-6\left(x+4\right)
Use the distributive property to multiply 2 by 2x-2.
7x+6-4=3\left(5x+10\right)-6\left(x+4\right)
Combine 3x and 4x to get 7x.
7x+2=3\left(5x+10\right)-6\left(x+4\right)
Subtract 4 from 6 to get 2.
7x+2=15x+30-6\left(x+4\right)
Use the distributive property to multiply 3 by 5x+10.
7x+2=15x+30-6x-24
Use the distributive property to multiply -6 by x+4.
7x+2=9x+30-24
Combine 15x and -6x to get 9x.
7x+2=9x+6
Subtract 24 from 30 to get 6.
7x+2-9x=6
Subtract 9x from both sides.
-2x+2=6
Combine 7x and -9x to get -2x.
-2x=6-2
Subtract 2 from both sides.
-2x=4
Subtract 2 from 6 to get 4.
x=\frac{4}{-2}
Divide both sides by -2.
x=-2
Divide 4 by -2 to get -2.
