Suppose the operations “#” and “t” are defined so that:
6 # = 20; 2 # = 4; 10 # = 36; and 5 t = 4.5; 10 t = 7; 8 t = 6.
Then what is n if 3 # # t = n?
We see that:
6 # = 20
2 # = 4
10 # = 36
x # = 4x – 4 = 4(x – 1)
2 # = 4
10 # = 36
x # = 4x – 4 = 4(x – 1)
Also:
5 t = 4.5
10 t = 7
8 t = 6
x t = x/2 + 2
So if 3 # # t = n, then
8 # t = n
28 t = n
16 = n
8 # t = n
28 t = n
16 = n
