    Answer:

    (-2,7)

    Step-by-step explanation:

    Bg subtitution method

    x+y=5

    x=5-y(1st eq)

    2x+y=3

    From 1st eq x=5-y

    2(5-y)+y=3

    10-2y+y=3

    10-y=3

    -y=3-10

    -y=-7

    y=7

    subtitute y value in 1st eq

    x+y=5

    x+7=5

    x=5-7

    x=-2

    so the solution is (-2,7)

    I hope this answer may help you
