5-10x=3-2\left(2-x\right)
Use the distributive property to multiply 5 by 1-2x.
5-10x=3-4+2x
Use the distributive property to multiply -2 by 2-x.
5-10x=-1+2x
Subtract 4 from 3 to get -1.
5-10x-2x=-1
Subtract 2x from both sides.
5-12x=-1
Combine -10x and -2x to get -12x.
-12x=-1-5
Subtract 5 from both sides.
-12x=-6
Subtract 5 from -1 to get -6.
x=\frac{-6}{-12}
Divide both sides by -12.
x=\frac{1}{2}
Reduce the fraction \frac{-6}{-12} to lowest terms by extracting and canceling out -6.
