    If y equals 2x - 3 in the second equation, than subsitute it in for y in the first.

    2x + 2x - 3 = 5

    4x - 3 = 5

    4x = 8

    x=2

    2 (2) + y = 5

    x = 2 and y = 1

    For the second equation, y=2x-3. Substituting this in, you get 2x+2x-3=5. Add the 2x's (4x), and add 3 to the 5 (8). You should get 4x=8, which will give you x=2.
