-x+5=25
Square both sides of the equation.
-x+5-5=25-5
Subtract 5 from both sides of the equation.
-x=25-5
Subtracting 5 from itself leaves 0.
-x=20
Subtract 5 from 25.
\frac{-x}{-1}=\frac{20}{-1}
Divide both sides by -1.
x=\frac{20}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-20
Divide 20 by -1.
