Step 1

Consider the following system of equations:

2x+5y=−8...(1)

x−y=−11...(2)

Multiply equation (2) by 2:

2x−2y=−22...(3)

Subtract equation (1) from equation (2):

7y=14

y=2

Substitute y in the equation (2):

x-2=-11

x=-9

Solution of the simultaneous equation is (−9,2).

Step 2

Hence, the answer is Yes.
