    So 2x-y=17

    x-y=10

    multiply second equation by - 1

    -x+y=-10

    add to first equation

    2x-y=17

    -x+y=-10

    2x-x+y-y=17-10

    x=7

    subsitute

    7-y=10

    subtract 7

    -y=3

    multiply - 1

    y=-3

    x=7

    y=-3

    2x - y = 17 ⇒ 2x - 1y = 17

    x - y = 10 ⇒ 2x - 2y = 20

    y = - 3

    2x - (-3) = 17

    2x + 3 = 17

    -3 - 3

    2x = 14

    2 2

    x = 7

    (x, y) = (7, - 3)
