3y = -2x - 19 ⇒ 2x + 3y = -19
-5x - 3y = -2 ⇒ <u>-5x - 3y = -2</u>
<u>-3x</u> = <u>-17</u>
-3 -3
x = 5²/₃
-5x - 3y = -2
-5(5²/₃) - 3y = -2
-28¹/₃ - 3y = -2
<u>+ 28¹/₃ + 28¹/₃
</u> <u /><u>-3y</u> = <u>26¹/₃
</u> -3 -3
y = -8⁷/₉
(x, y) = (5²/₃, -8⁷/₉)

3y=-2x-19 -5x-3y=-2-5x - (-2x - 19) = -2
-5x + 2x + 19 = -2
-3x = -21
x = 7
3y = -2(7) - 19
3y = -14 - 19
3y = 33
y = 11
