Answer:

x = 2

y = 5

Explanation:

-x - 3y = -17

2x - 6y = -26

--------------------

(-x - 3y = -17) × 2

-2x - 6y = -34

-------------------------

-2x - 6y = -34

2x - 6y = -26

-------------------------

-12y = -60

÷-12 ÷-12

-------------------------------

y = 5

-x - 3y = -17

-x - 3(5) = -17

-x - 15 = -17

+15 + 15

--------------------

-x = -2

÷-1 ÷-1

-----------

x = 2

I hope this helps!
