16-4x+6=4x
Use the distributive property to multiply -2 by 2x-3.
22-4x=4x
Add 16 and 6 to get 22.
22-4x-4x=0
Subtract 4x from both sides.
22-8x=0
Combine -4x and -4x to get -8x.
-8x=-22
Subtract 22 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-22}{-8}
Divide both sides by -8.
x=\frac{11}{4}
Reduce the fraction \frac{-22}{-8} to lowest terms by extracting and canceling out -2.
