If w=4x, 2x=3y, and z=y/w, then w/z =
A. 4w
B. 20x
C. 28x
D. 24y
E. 36y

my way:

2x = 3y means y = 2/3x insert in z=y/w along with w=4x makes
z=(2/3x)/4x => z=1/6 insert in w/z along with w=4x => 4x/(1/6) => 24x ??? but it is not ??? why ???

24x can be further simplified using the equation 2x = 3y which will give you (24x * 3y)/2x => 36y

E...

w=4x=4*(3/2)y
=6y.

therefore, w/z=6y*(y/w)=6w=24x=12*2x=36y.
