    Answer:

    hope this helps u

    Step-by-step explanation:

    here i am doing by elimination

    2x-y=5

    5x-y = 11 here change of sign

    (-)  (+) = (-)

    —————–

    -3x=-6

    x = -6/-3

    x = 2

    2x – 5 = y

    2*2-5 = y

    4-5 = y

    y = -1

    verification

    2*2-[-1] =5

    4+1=5

    5=5
