in math?

In mathematics, having one solution means that there is a single value that satisfies an equation or inequality. For example, a linear equation like 2x + 3 = 7 would have one solution, x = 2, because there is only one value of x that makes the equation true. If an equation has multiple solutions, it means there are several values of the variable that can satisfy the equation. Having one solution in math indicates that there is a unique and specific answer to the mathematical problem.
