0.75x+4.5-1.25x=2.5
Subtract 1.25x from both sides.
-0.5x+4.5=2.5
Combine 0.75x and -1.25x to get -0.5x.
-0.5x=2.5-4.5
Subtract 4.5 from both sides.
-0.5x=-2
Subtract 4.5 from 2.5 to get -2.
x=\frac{-2}{-0.5}
Divide both sides by -0.5.
x=\frac{-20}{-5}
Expand \frac{-2}{-0.5} by multiplying both numerator and the denominator by 10.
x=4
Divide -20 by -5 to get 4.
