Use the following equations to construct an equation for w that involves only the variables a and b.
A) X*W = Y*T
B) X/A=B
C) A^3*y=B
D) A^2= T*B

2. 1) w=yt/x

x=ab
y=b/a^3
t=a^2/b

now put the tree equations above at the first.

$W = \dfrac{YT}{X}$

$X = AB$

$Y = \dfrac{B}{A^3}$

$T = \dfrac{A^2}{B}$

Using this sub in the first equation

$W = \dfrac{\dfrac{B}{A^3} \cdot \dfrac{A^2}{B}}{AB}$

I'll leave it up to you to simplify
