 2x - 3y = 9   ⇒ -10x + 15y = -45
-5x - 3y = 30 ⇒ <u>-10x -   6y =   60</u>
                                      <u>9y</u> = <u>15</u>
                                       9      9
                                       y = 1 2/3
                     2x - 3(1 2/3) = 9
                               2x - 5 = 9
                               <u>     +5  +5</u>
                                     <u>2x</u> = <u>4</u>
                                      2     2
                                       x = 2
                                 (x, y) = (2, 1 2/3)

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
