    Answer:

    x = 5 and y= 15

    Step-by-step explanation:

    3x + 2y = 45

    4x – y = 5 (multiple both sides by 2)

    or

    3x + 2y = 45

    8x – 2y = 10

    ——————–( add side with side)

    11x + 0 = 55

    or x= 55/11 = 5

    replace x =5 into 4x – y = 5 we have 4*5 – y = 5

    20 – y = 5 or y = 20- 5= 15

    So x = 5 and y= 15

    Have a good day
