Multiple choice general knowledge science & technology Solve the equations.. 5x + 3y = 65 13x + 4y = 150.. find the value of x and y? x = 4, y = 3 x = 10, y = 5 x = 2 , y = 6 x = 3, y = 2 Reveal answer Fill a bubble to check yourself B Correct answer Explanation Solving by elimination: multiply first equation by 4 (20x + 12y = 260) and second by 3 (39x + 12y = 450). Subtracting gives 19x = 190, so x = 10. Substituting back: 5(10) + 3y = 65, so 3y = 15 and y = 5.
