Detailed Solution

Concept: We'll start by assuming that the given equation has a solution, which is a number we can substitute for a variable to make the equation true, i.e., the left-hand side of the equation equals the right-hand side. To determine the necessary value, we will therefore change the values of x and y in the above equation.
We are aware that an equation contains some variables and constants that tell us that two sides are equal, and that a solution is a number we may substitute for a variable to cause the equation to hold true—that is, for the equation's left and right sides to be equal.
