Answer:

D. (4,-1)

Explanation:

So, we have these two equations:

2x + y = 7

x - 2y = 6

Isolate x in the second equation:

x = 2y + 6

Substitute it into the first equation:

2(2y + 6) + y = 7

4y + 12 + y = 7

5y + 12 = 7

5y = -5

y = -1

Plug y back into the second equation:

x - 2(-1) = 6

x + 2 = 6

x = 4

So, the correct answer is D. (4,-1)

Hope this helps!!
