If (2x+3y=33) and (4x-y=3), what will be the solution?

Answer and explanation

Correct answer: (3, 9)

From the second equation, y = 4x - 3. Substituting this into the first equation gives 2x + 3(4x - 3) = 33, so 14x = 42 and x = 3. Then y = 4(3) - 3 = 9. Hence, the solution is (3, 9). Option (5, 6) satisfies the second equation, but it gives 2x + 3y = 28, not 33. Exam tip: Always verify the ordered pair in both original equations.
