    Answer:x=4 y=3

    Step-by-step explanation:

    5x-4y=8 ... (1)

    2x+y=11 ... (11)

    From (11) y=11-2x

    Substitute y=11-2x in 5x-4y=8

    5x-4y=8

    5x-4 (11-2x) = 8

    Open bracket

    5x-44+8x=8

    Collect like terms

    5x+8x=8+44

    13x=52

    Divide both sides by 13

    13x/13=52/13

    x=4

    Substitute x=4 in 2x+y=11

    2 (4) + y=11

    8+y=11

    Collect like terms

    y=11-8

    y=3
