    x = 10 and y = - 1

    Step-by-step explanation:

    Rewrite your second equation Y = - 2x + 19 then plug it into the first equation.

    x - (-2x + 19) = 11

    x + 2x - 19 = 11

    3x - 19 = 11

    3x = 30

    x = 10

    The plug that answer into the first equation and solve.

    10 - y = 11

    -y = 1

    y = - 1
