Answer 1

Answer:

$\displaystyle [2, -3]$

Step-by-step explanation:

{2x - 3y = 13

{x + 2y = −4

⅔[2x - 3y = 13]

{1⅓x - 2y = 8⅔

{x + 2y = −4

____________

$\displaystyle \frac{2\frac{1}{3}x}{2\frac{1}{3}} = \frac{4\frac{2}{3}}{2\frac{1}{3}}$

$\displaystyle x = 2$[Plug this back into both equations above to get the y-coordinate of −3]; $\displaystyle -3 = y$

* This is using the Elimination Method.
