15d+875-225d=5
Subtract 225d from both sides.
-210d+875=5
Combine 15d and -225d to get -210d.
-210d=5-875
Subtract 875 from both sides.
-210d=-870
Subtract 875 from 5 to get -870.
d=\frac{-870}{-210}
Divide both sides by -210.
d=\frac{29}{7}
Reduce the fraction \frac{-870}{-210} to lowest terms by extracting and canceling out -30.
