7x=4y
Swap sides so that all variable terms are on the left hand side.
\frac{7x}{7}=\frac{4y}{7}
Divide both sides by 7.
x=\frac{4y}{7}
Dividing by 7 undoes the multiplication by 7.
4y=7x
The equation is in standard form.
\frac{4y}{4}=\frac{7x}{4}
Divide both sides by 4.
y=\frac{7x}{4}
Dividing by 4 undoes the multiplication by 4.
