    I would isolate x in the first equation:

    x = 3y + 1

    For the second equation, you could just substitute the x inside:

    3x - 5y = 11

    3 (3y + 1) - 5y = 11

    9y + 3 - 5y = 11

    4y + 3 = 11

    4y = 8

    y = 2

    Using the y = 2, we can find x.

    x = 3y + 1

    x = 3 (2) + 1

    x = 7

    x = 7 and y = 2
