\sqrt{2x}+5=20
Swap sides so that all variable terms are on the left hand side.
\sqrt{2x}=20-5
Subtract 5 from both sides.
\sqrt{2x}=15
Subtract 5 from 20 to get 15.
2x=225
Square both sides of the equation.
\frac{2x}{2}=\frac{225}{2}
Divide both sides by 2.
x=\frac{225}{2}
Dividing by 2 undoes the multiplication by 2.
