Answer:

x = 3

y = -1

( 3, -1 )

Step-by-step explanation:

5x + 2y = 13

3x - y = 10

<em>Multiply "3x - y = 10 " by 2</em>

5x + 2y = 13

6x - 2y = 20

<em>Cancel out +2y and -2y</em>

11x = 33

<em>Divide both sides by 11</em>

x = 3

<h2><em><u>Substitute Into any equation:</u></em></h2>

3(3) - y = 10

9 - y = 10

-y = 1

y = -1
