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