Answer:

infinitely many solutions

Explanation:

4x - 5y = - 20 → (1)

- 4x + 5y = 20 → (2)

add (1) and (2) term by term

0 + 0 = 0

0 = 0 ← true statement

this indicates the system has infinitely many solutions

We see : 4x - 5y = -20

We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y

Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20

And -4x + 5y is indeed 20, so the answer is infinitely many solutions.
