    You can use the substitution method. Using the first equation in terms of y,

    y = 5 - x

    Substitute this to the second equation to get the value of x.

    x - 2 (5 - x) = 2

    x - 10 + 2x = 2

    3x = 2 + 10

    3x = 12

    x = 4

    For y, just substitute the value of x that we have used in the first equation.

    y = 5 - 4 = 1

    Therefore, in coordinate form, that is (4,1)
