Help me with another math question

Answer 1

x = 3

y = -1

( 3, -1 )

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
