-\sqrt{5x}+1-1=-9-1
Subtract 1 from both sides of the equation.
-\sqrt{5x}=-9-1
Subtracting 1 from itself leaves 0.
-\sqrt{5x}=-10
Subtract 1 from -9.
\frac{-\sqrt{5x}}{-1}=-\frac{10}{-1}
Divide both sides by -1.
\sqrt{5x}=-\frac{10}{-1}
Dividing by -1 undoes the multiplication by -1.
\sqrt{5x}=10
Divide -10 by -1.
5x=100
Square both sides of the equation.
\frac{5x}{5}=\frac{100}{5}
Divide both sides by 5.
x=\frac{100}{5}
Dividing by 5 undoes the multiplication by 5.
x=20
Divide 100 by 5.
