4510+75.25x=300.75x
Anything plus zero gives itself.
4510+75.25x-300.75x=0
Subtract 300.75x from both sides.
4510-225.5x=0
Combine 75.25x and -300.75x to get -225.5x.
-225.5x=-4510
Subtract 4510 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-4510}{-225.5}
Divide both sides by -225.5.
x=\frac{-45100}{-2255}
Expand \frac{-4510}{-225.5} by multiplying both numerator and the denominator by 10.
x=20
Divide -45100 by -2255 to get 20.
