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
Plug x as -4y in second equation:
20y = - 5(-4y)
20y = 20y
0 = 0
L.H.S = R.H.S
True for all y.
Therefore true for all x.
x=1 y=(-1/2) putting those in 20x1=20 so 20= then you put -1/2 and multiply it by the -5 that would be your answer
