    You can solve it using the elimination method:

    2x -3y = 61
    2x +y = -7 * (-1)

    2x -3y = 61
    -2x -y = +7

    The x will disappear:

    -4y = 68
    y = 68/-4
    y = -17

    With Y value, use it on either equation:
    2x + (-17) = -7
    2x = -7 + 17
    2x = 10
    x = 10/2
    x = 5
    DEHUMANIZE YOURSELF
    AND FACE TO BLOODSHED
