    I not entirely sure by what means you are trying to solve the equation possibly you meant elimination. but the answer is x=-6 and y=-23

    Y = 3x - 5 ⇒ 3x + y = 5 ⇒ 6x + 2y = 10

    2x - y = 11 ⇒ 2x - y = 11 ⇒ 6x - 3y = 33

    5y = - 23

    5 5

    y = - 4 3/5

    3x - 4 3/5 = 5

    +4 3/5 + 4 3/5

    3x = 9 3/5

    3 3

    x = 3 1/5

    (x, y) = (3 1/5, - 4 3/5)
