\sqrt{m+15}+1-1=5-1
Subtract 1 from both sides of the equation.
\sqrt{m+15}=5-1
Subtracting 1 from itself leaves 0.
\sqrt{m+15}=4
Subtract 1 from 5.
m+15=16
Square both sides of the equation.
m+15-15=16-15
Subtract 15 from both sides of the equation.
m=16-15
Subtracting 15 from itself leaves 0.
m=1
Subtract 15 from 16.
