    (2,3)

    Step-by-step explanation:

    Substitute y = 2x - 1 in the equation y = 5x - 7

    2x - 1 = 5x - 7

    2x - 1 + 7 = 5x

    2x + 6 = 5x

    6 = 5x - 2x

    6 = 3x

    3x = 6

    x = 6/3

    x = 2

    Substitute the value of x in, y = 2x - 1

    y = 2*2 - 1

    y = 4 - 1

    y = 3
