To solve the system of equations by the substitution method, we can start by solving one equation for one variable and then substituting that expression into the other equation.Let's solve the second equation for y:
Now, we can substitute this expression for y into the first equation:
Now that we have the value of x, we can substitute it back into the expression for y:
Therefore, the solution set is
