Solution
For `"z"/3`, the table can be constructed as follows.
-
z
`"z"/3`
8
`8/3 = 2 2/3`
9
`9/3 = 3`
10
`10/3 = 3 1/3`
11
`11/3 = 3 2/3`
12
`12/3 = 4`
13
`13/3 = 4 1/3`
14
`14/3 = 4 2/3`
15
`15/3 = 5`
16
`16/3 = 5 1/3`
By inspection, we can find that z = 12 is the solution of the above equation as for z = 12, `"z"/3` = 4
