-9+q=5r-10
Swap sides so that all variable terms are on the left hand side.
q=5r-10+9
Add 9 to both sides.
q=5r-1
Add -10 and 9 to get -1.
5r=-9+q+10
Add 10 to both sides.
5r=1+q
Add -9 and 10 to get 1.
5r=q+1
The equation is in standard form.
\frac{5r}{5}=\frac{q+1}{5}
Divide both sides by 5.
r=\frac{q+1}{5}
Dividing by 5 undoes the multiplication by 5.
