3\left(2-3x-\left(-6\right)-4\right)-4\left(1-2x\right)=4-5x
To find the opposite of 3x-6, find the opposite of each term.
3\left(2-3x+6-4\right)-4\left(1-2x\right)=4-5x
The opposite of -6 is 6.
3\left(8-3x-4\right)-4\left(1-2x\right)=4-5x
Add 2 and 6 to get 8.
3\left(4-3x\right)-4\left(1-2x\right)=4-5x
Subtract 4 from 8 to get 4.
12-9x-4\left(1-2x\right)=4-5x
Use the distributive property to multiply 3 by 4-3x.
12-9x-4+8x=4-5x
Use the distributive property to multiply -4 by 1-2x.
8-9x+8x=4-5x
Subtract 4 from 12 to get 8.
8-x=4-5x
Combine -9x and 8x to get -x.
8-x+5x=4
Add 5x to both sides.
8+4x=4
Combine -x and 5x to get 4x.
4x=4-8
Subtract 8 from both sides.
4x=-4
Subtract 8 from 4 to get -4.
x=\frac{-4}{4}
Divide both sides by 4.
x=-1
Divide -4 by 4 to get -1.
