    If your in algebra 1 then i'm pretty sure you subtract the 2x and that cancels and subract the 2x with the 9 and you have - 3y = - 2x+9 so you divide - 3 to the - 3y, the - 2x and positive 9 and your answer will be y=2/3x-3

    2x - 3y = 9 ⇒ - 10x + 15y = - 45

    -5x - 3y = 30 ⇒ - 10x - 6y = 60

    9y = 15

    9 9

    y = 1 2/3

    2x - 3 (1 2/3) = 9

    2x - 5 = 9

    +5 + 5

    2x = 4

    2 2

    x = 2

    (x, y) = (2, 1 2/3)
