Question

Which statements are true about the ordered pair (-1,5) and the system of equations x+y=4 x-y=-6​

Answer 1

-1+5=4
And
-5+1=-4
So it’s x+y=4

Answer 2

A) x+y=4

B) x-y=-6​

We add both equations and get

2x = -2 so x = -1

and y = 5

So the ordered pair (-1, 5) is the solution to the equations.
