Joint variation:
y varies jointly as x and z
------------------------------
y = 56, x = 8, z = 1
------------------
y = ?, z = 4, x = 4

Combined variation:
y varies directly as x and inversely as z
-------------------------------------
y = 32, x = 36, z = 9
---------------------
y = ?, x = 25, z = 5
