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
