Answer:

x = -2

y = 7

Step-by-step explanation:

-x + 7y = 51

-x - 4y = -26

=> -x + 7y = 51

-x - 4y = -26

=> -x + 7y = 51

x + 4y = 26

=> 7y = 51

4y = 26

=> 7y + 4y = 51 + 26

=> 11y = 77

=> y = 7

=> -x + 7(7) = 51

=> -x + 49 = 51

=> -x = 51 - 49

=> -x = 2

=> x = -2

Hoped this helped.
