Step-by-step explanation:
We need to check each u value to say if each one is correct...
8
u - 27
when u = 33
8
33 - 27
8
6
and it's true!
So, 33 is solution
when u = 39
8
39 - 27
8
12
It isn't true. No solution!
When u = 31
8
31 - 27
8
4
It's true and it also is a solution.
when u = 35
8
35 - 27
8
8
it's true and it also is a solution.
