    Answer:

    {x,y}={4,7}

    Step-by-step explanation:

    3x – y = 5

    x+ 4y = 32

    y + 3x = 5   ,      4y + x = 32  

    x = -4y + 32

    3•(-4y+32) – y = 5

    – 13y = -91

    13y = 91  

     y = 7

    x = -4y+32

     y = 7

    x = -4(7)+32 = 4

    so the final solution is:

    ⇒x = -4(7)+32 = 4
