30x=60y
The equation is in standard form.
\frac{30x}{30}=\frac{60y}{30}
Divide both sides by 30.
x=\frac{60y}{30}
Dividing by 30 undoes the multiplication by 30.
x=2y
Divide 60y by 30.
60y=30x
Swap sides so that all variable terms are on the left hand side.
\frac{60y}{60}=\frac{30x}{60}
Divide both sides by 60.
y=\frac{30x}{60}
Dividing by 60 undoes the multiplication by 60.
y=\frac{x}{2}
Divide 30x by 60.
