15x=20y
The equation is in standard form.
\frac{15x}{15}=\frac{20y}{15}
Divide both sides by 15.
x=\frac{20y}{15}
Dividing by 15 undoes the multiplication by 15.
x=\frac{4y}{3}
Divide 20y by 15.
20y=15x
Swap sides so that all variable terms are on the left hand side.
\frac{20y}{20}=\frac{15x}{20}
Divide both sides by 20.
y=\frac{15x}{20}
Dividing by 20 undoes the multiplication by 20.
y=\frac{3x}{4}
Divide 15x by 20.
