3\times 3\left(x+6\right)=2\left(4x-5\right)+4\left(2x+2\right)
Multiply both sides of the equation by 12, the least common multiple of 4,6,3.
9\left(x+6\right)=2\left(4x-5\right)+4\left(2x+2\right)
Multiply 3 and 3 to get 9.
9x+54=2\left(4x-5\right)+4\left(2x+2\right)
Use the distributive property to multiply 9 by x+6.
9x+54=8x-10+4\left(2x+2\right)
Use the distributive property to multiply 2 by 4x-5.
9x+54=8x-10+8x+8
Use the distributive property to multiply 4 by 2x+2.
9x+54=16x-10+8
Combine 8x and 8x to get 16x.
9x+54=16x-2
Add -10 and 8 to get -2.
9x+54-16x=-2
Subtract 16x from both sides.
-7x+54=-2
Combine 9x and -16x to get -7x.
-7x=-2-54
Subtract 54 from both sides.
-7x=-56
Subtract 54 from -2 to get -56.
x=\frac{-56}{-7}
Divide both sides by -7.
x=8
Divide -56 by -7 to get 8.
