1+\sqrt{25-m}=5
Swap sides so that all variable terms are on the left hand side.
\sqrt{25-m}=5-1
Subtract 1 from both sides.
\sqrt{25-m}=4
Subtract 1 from 5 to get 4.
-m+25=16
Square both sides of the equation.
-m+25-25=16-25
Subtract 25 from both sides of the equation.
-m=16-25
Subtracting 25 from itself leaves 0.
-m=-9
Subtract 25 from 16.
\frac{-m}{-1}=-\frac{9}{-1}
Divide both sides by -1.
m=-\frac{9}{-1}
Dividing by -1 undoes the multiplication by -1.
m=9
Divide -9 by -1.
