650+35x-45.5x=0
Subtract 45.5x from both sides.
650-10.5x=0
Combine 35x and -45.5x to get -10.5x.
-10.5x=-650
Subtract 650 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-650}{-10.5}
Divide both sides by -10.5.
x=\frac{-6500}{-105}
Expand \frac{-650}{-10.5} by multiplying both numerator and the denominator by 10.
x=\frac{1300}{21}
Reduce the fraction \frac{-6500}{-105} to lowest terms by extracting and canceling out -5.
