What does solution of an equation mean in math?

In mathematics, a solution of an equation refers to a value or set of values that satisfy the equation, making it true when substituted into the equation. For example, in the equation (x + 2 = 5), the solution is (x = 3) because substituting 3 for (x) results in a true statement. Solutions can be single numbers, intervals, or sets, depending on the nature of the equation.
