You can put this solution on YOUR website!
g, t, z
Gorillas, Tigers, Zebras
Not clear what you want with r.

The description gives this system:
system%28g%2Ft=4%2Ct=z%2B4%29
(or maybe system%28g%2Fr=4%2Cr=z%2B4%29)

Find g.
g=4t
g=4%28z%2B4%29
g=4z%2B16
-
Maybe you want r for number of tigers.
r=z%2B4
z=r-4
-
g=4%28r-4%29%2B16
4r-16%2B16
g=4r
