Answer:

x = -1

y = -4

Step-by-step explanation:

Known :

  • 2x - y = 2
  • 5x + y = -9

Asked :

  • x = ?
  • y = ?

Solution :

2x - y = 2

5x + y = -9

Using the elimination method, we can find the value of x.

2x - y = 2

5x + y = -9

_________+

7x = -7

x = -1

Then, we can use substitution method to find the value of y

5x + y = -9

5(-1) + y = -9

-5 + y = -9

y = -9 + 5

y = -4

Conclusion :

So in conclusion, the value of x and y is -1 and -4
