    Answer:

    There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

    2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\

    Now we will solve for y using what we got for x.

    2(3) - 2y = 6\\\\6 - 2y = 6\\\\-2y = 0\\\\y = 0

    Solution:

    A: (0, 3)
