 Solve for X:

1) X + Y = 12                                                                                                                                                        X  -  Y =  6                                                                                                                                                        =========


2) X + Y = 15

    X  - Y =  3                                                                                                                                                          =========

    1)
    First, you add them together, which gives you 2x = 18, then you simplify it to make it x = 9. This is your answer.

    2)
    For this one, it is similar. You add them together and you get 2x = 18, and x = 9.

    These are your 2 answers.
