    Step-by-step explanation:

    5x+3y = 12 …1

    4x-5y = 17 …2

    …1 × 5 both sides of the equation

    25x + 15y = 60 …3

    …2 × 3 both sides of the equation

    12x – 15y = 51 …4

    …3 + …4

    25x + 15y + 12x -15y = 60+51

    37x = 111

    x = 111/37 = 3

    replace x = 3 in …1

    y = …….
