It depends on what you mean by solve: simplify, evaluate or rationalise the denominator. The answer will also depend on the radical expression.
to simplify the radicand
Simplifying radical expression is simply performing the operations in similar or like terms. This helps eliminate confusion and makes the equation simpler and easier to manage.
No, you cannot add or subtract under the radical. The radical represents the square root function, and it only operates on the number or expression that is inside the radical. To add or subtract, you need to simplify the expressions inside the radical first.

Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..

"rationalizing" the denominator
It is easier to work with simplified radicals just as it is easier to work with simplified fractions. A fundamental rule for math is to simplify whenever possible, as much as possible.

Suppose the expression under the radical sign is y. Then the first step is to simplify y. Next find a term (or expression) x, such that y = x^2*z for some term (or expression) z. Then x*sqrt(z) is a simplification of sqrt(y).
No, you cannot add or subtract under the radical. The radical represents the square root function, and it only operates on the number or expression that is inside the radical. To add or subtract, you need to simplify the expressions inside the radical first.
Radical (3x) = radical(x) * radical(3).
