Question

I need an explanation for my math problem. I am struggling...
The problem states :

Fill in the blanks so that the solution of the system is (5, 5).
___ x + y = -5
y = -x + ____

Answer 1

Answer:

-2x+y=-5    y=-x+10

Step-by-step explanation:

Both x and y must be 5 because the point given is (5,5).

So 5(___) +5=-5

5(___) =-10

___ = -2

Similarly for the second blank:

5=-5+___

___=10
