-8+13\sqrt{q+1}=5
Swap sides so that all variable terms are on the left hand side.
13\sqrt{q+1}=5+8
Add 8 to both sides.
13\sqrt{q+1}=13
Add 5 and 8 to get 13.
\sqrt{q+1}=\frac{13}{13}
Divide both sides by 13.
\sqrt{q+1}=1
Divide 13 by 13 to get 1.
q+1=1
Square both sides of the equation.
q+1-1=1-1
Subtract 1 from both sides of the equation.
q=1-1
Subtracting 1 from itself leaves 0.
q=0
Subtract 1 from 1.
