\frac{y}{4}=x
Swap sides so that all variable terms are on the left hand side.
\frac{1}{4}y=x
The equation is in standard form.
\frac{\frac{1}{4}y}{\frac{1}{4}}=\frac{x}{\frac{1}{4}}
Multiply both sides by 4.
y=\frac{x}{\frac{1}{4}}
Dividing by \frac{1}{4} undoes the multiplication by \frac{1}{4}.
y=4x
Divide x by \frac{1}{4} by multiplying x by the reciprocal of \frac{1}{4}.
