    You can use an elimination or a substitution.

    Elimination:
    Code:
     x + y = 10
 x - y =  6
2x + 0 = 16
    or

    Code:
     x +  y = 10
-x +  y = -6
 0 + 2y =  4
    Substitution:
    x - y = 6
    x = 6 - y

    Plug in the first equation:
    (6 - y) + y = 10

    There are many ways to solve simultaneous equations. You just do the one you're more confident with.
