From TomV: y = kx/z²
8 = k(4/9) → k = 72/4 = 18
y = 18x/...

y = kx/z²
8 = k(4/9) → k = 72/4 = 18
y = 18x/z²
y = 18(6/4) = 27
ans: 27

From derfram: y = k(x/z²)
8 = k(4/3²)
8 = k(4/9)
k = 18
y =...

y = k(x/z²)
8 = k(4/3²)
8 = k(4/9)
k = 18
y = k(x/z²)
y = 18[6/(2)²]
y = 18(6/4)
y = 27

From Como: 
y = k x / z²
k = y z² / x = 8 x 9 / 4...

y = k x / z²
k = y z² / x = 8 x 9 / 4 = 18
y = 18 x 6 / 4
y = 27
