Answer:

The system of equations has infinite solutions. True for all y and x.

Given equations:

x + 4y = 0

20y = - 5x

Make x the subject for equation 1:

x + 4y = 0

x = -4y

Plug x as -4y in second equation:

20y = - 5x

20y = - 5(-4y)

20y = 20y

0 = 0

L.H.S = R.H.S

True for all y.

Therefore true for all x.
