3\left(3-x\right)-\left(2x-2\right)=36-3x
Multiply both sides of the equation by 9, the least common multiple of 3,9.
9-3x-\left(2x-2\right)=36-3x
Use the distributive property to multiply 3 by 3-x.
9-3x-2x-\left(-2\right)=36-3x
To find the opposite of 2x-2, find the opposite of each term.
9-3x-2x+2=36-3x
The opposite of -2 is 2.
9-5x+2=36-3x
Combine -3x and -2x to get -5x.
11-5x=36-3x
Add 9 and 2 to get 11.
11-5x+3x=36
Add 3x to both sides.
11-2x=36
Combine -5x and 3x to get -2x.
-2x=36-11
Subtract 11 from both sides.
-2x=25
Subtract 11 from 36 to get 25.
x=\frac{25}{-2}
Divide both sides by -2.
x=-\frac{25}{2}
Fraction \frac{25}{-2} can be rewritten as -\frac{25}{2} by extracting the negative sign.
