There are 23 fish. Gups are 3 more than Zfish. 2 times the Z-fish as Golds. How many of each? I see there are 8 Zfish (Z), 11 Gups (G) & 4 Golds (GF). When I try the equation it's wrong.. Z + (Z+3) +(Z/2) = 23 equation? So Z + (Z/2) = 20/2 (=10).... not correct..so.. answer should be 12 (if Z=8, G =11, GF=4. help?
