Steps to solve an equation with radicals:

1. Isolate the radical expression involving the variable on one side of the equation. If more than one radical expression involves the variable, then isolate one of them.

2. Raise both sides of the equation to the index of the radical.

3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.
