Solving for 5x:


The values for x will be


To find all the solutions, we'll give n values of 0, 1, 2,... until x stops belonging to the interval 
For n=0


For n=1


For n=2


For n=3


For n=4


For n=5 we would find values such as


which don't lie in the interval

Answer:
25 shelves
Step-by-step explanation:
The number of shelves he can make is basically the total amount of wood he has divided by the amount of wood it takes per shelf.
Given in the problem:
Total Amount of Wood = 15 meters
Wood Amount needed per Shelf = 3/5
Hence,
Number of Shelves = 15 divided by 3/5
Note: dividing by a fraction means multiplying by its reciprocal (upside down version)
We show the division below:
Number of Shelves = 
So Tom can make 25 shelves
