STP=90
The equation is in standard form.
\frac{STP}{ST}=\frac{90}{ST}
Divide both sides by ST.
P=\frac{90}{ST}
Dividing by ST undoes the multiplication by ST.
PTS=90
The equation is in standard form.
\frac{PTS}{PT}=\frac{90}{PT}
Divide both sides by TP.
S=\frac{90}{PT}
Dividing by TP undoes the multiplication by TP.
