    (x, y) = (2,2)

    Step-by-step explanation:

    5x+3y=16 / *5

    3x-5y=-4 / *3

    25x+15y=80 (1)

    9x-15y=-12 (2)

    (1) + (2) : 34x=68

    9x-15y=-12

    x=68/34

    9x-15y=-12

    x=2

    9*2-15y=-12

    x=2

    18-15y=-12

    x=2

    -15y=-12-18

    x=2

    -15y=-30

    x=2

    y=-30 / (-15)

    x=2

    y=2

    (x, y) = (2,2)
