460-8x-20\times 2=0
Subtract 40 from 500 to get 460.
460-8x-40=0
Multiply 20 and 2 to get 40.
420-8x=0
Subtract 40 from 460 to get 420.
-8x=-420
Subtract 420 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-420}{-8}
Divide both sides by -8.
x=\frac{105}{2}
Reduce the fraction \frac{-420}{-8} to lowest terms by extracting and canceling out -4.
