Answer:

x = 3

y = -1

( 3, -1 )

Step-by-step explanation:

5x + 2y = 13

 3x - y = 10

Multiply "3x - y = 10 " by 2

5x + 2y = 13

6x - 2y = 20

Cancel out +2y and -2y

11x = 33

Divide both sides by 11

x = 3

Substitute Into any equation:

 3(3) - y = 10

     9 - y = 10

         -y = 1

          y = -1
