\frac{38}{7}q=r
The equation is in standard form.
\frac{\frac{38}{7}q}{\frac{38}{7}}=\frac{r}{\frac{38}{7}}
Divide both sides of the equation by \frac{38}{7}, which is the same as multiplying both sides by the reciprocal of the fraction.
q=\frac{r}{\frac{38}{7}}
Dividing by \frac{38}{7} undoes the multiplication by \frac{38}{7}.
q=\frac{7r}{38}
Divide r by \frac{38}{7} by multiplying r by the reciprocal of \frac{38}{7}.
r=\frac{38}{7}q
Swap sides so that all variable terms are on the left hand side.
