qp=100q
The equation is in standard form.
\frac{qp}{q}=\frac{100q}{q}
Divide both sides by q.
p=\frac{100q}{q}
Dividing by q undoes the multiplication by q.
p=100
Divide 100q by q.
pq-100q=0
Subtract 100q from both sides.
\left(p-100\right)q=0
Combine all terms containing q.
q=0
Divide 0 by -100+p.
