    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.
