Question

(5, -9) is a solution to the system x + y = -4
x - y = 4

true or false

Answer 1

Answer:

false

Step-by-step explanation:

This is a solution to the first equation because

5+-9=-4

-4=-4

however, if you plug it into the next equation, it becomes false.

5--9=4

14=4

this does not make sense.
