1.5d+8.75-2.25d=5
Subtract 2.25d from both sides.
-0.75d+8.75=5
Combine 1.5d and -2.25d to get -0.75d.
-0.75d=5-8.75
Subtract 8.75 from both sides.
-0.75d=-3.75
Subtract 8.75 from 5 to get -3.75.
d=\frac{-3.75}{-0.75}
Divide both sides by -0.75.
d=\frac{-375}{-75}
Expand \frac{-3.75}{-0.75} by multiplying both numerator and the denominator by 100.
d=5
Divide -375 by -75 to get 5.
