xrad=30
Swap sides so that all variable terms are on the left hand side.
drxa=30
The equation is in standard form.
\frac{drxa}{drx}=\frac{30}{drx}
Divide both sides by xrd.
a=\frac{30}{drx}
Dividing by xrd undoes the multiplication by xrd.
xrad=30
Swap sides so that all variable terms are on the left hand side.
arxd=30
The equation is in standard form.
\frac{arxd}{arx}=\frac{30}{arx}
Divide both sides by xra.
d=\frac{30}{arx}
Dividing by xra undoes the multiplication by xra.
