    x = 3

    y = - 5

    Step-by-step explanation:

    5x+2y = 5 equation 1

    3 х - у = 14 equation 2

    using equation 2 we have:

    3x - 14 = y equation 3

    using equation 3 in equation 1 we have:

    5x + 2 (3x - 14) = 5

    5x + 6x - 28 = 5

    11x = 5+28

    11x = 33

    x = 33/11

    x = 3

    using equation 3 we have:

    3 (3) - 14 = y

    y = 9-14

    y = - 5
