    Answer:

    x = 5

    y = -4/3

    Step-by-step explanation:

    Solve by elimination by adding the two equations together:

    2x + 3y = 6

    x – 3y = 9

    3y and -3y will cancel out. Then, solve for x:

    3x = 15

    x = 5

    Plug in 5 as x into one of the equations, then solve for x:

    x – 3y = 9

    5 – 3y = 9

    -3y = 4

    y = -4/3

    So, the answer is x = 5 and y = -4/3
