Treat this as a pair of simultaneous linear equations. A reliable method is elimination: choose one variable, multiply the equations if needed, and add or subtract so that one variable disappears. Solving the system gives x and y values that satisfy both equations at the same time. Here the solution is x=4, y=6. We should verify it, not just stop after solving: substituting the ordered values into 3x + 2y = 24 and 2x + 2y = 20 makes both equations true. That confirmation shows the selected answer is correct.
