    2x - y = 6

    5x + 10y = - 10

    (2x - y = 6) * 5

    10x - 5y = 30

    (5x + 10y = - 10) * 2

    10x + 20y = - 20

    If we subtract the last 2 equations,

    30y = - 50

    y = - (5/3)

    2x - (-5/3) = 6

    2x + (5/3) = 6

    2x = 6 - (5/3)

    2x = (18-5) / 3

    2x = 13/3

    x = 13/6
