    x = 22.75 & y = - 15

    Step-by-step explanation:

    The equations are;

    7x - 2y = 37 (equation 1)

    4x + y = 19 (equation 2)

    Now multiplying equation 1 by 4,

    28x - 8y = 148 (equation 3)

    Now multiplying equation 2 by 7,

    28x + 7y = 133 (equation 4)

    Subtracting equation 3 with with equation 4,

    we get x = 22.75 & y = - 15
