            @MathLover1 chose the most complicated and convoluted/confused way to present the solution.

            I will choose the most simple and straightforward way. 


Let Timothy be "t" years old.


Then Joseph is  (t+5)  years old and Mathew is  (t+7)  years old, according to the condition.


The numbers follow in this ascending order  t,  t+5,  t+7.  


Hence, the names ordering is this: Timothy, Joseph, Mathew, from youngest to oldest.

PERSON            AGE
Joseph           (m-7)+5
Timothy          m-7
Mathew            m

"Write the names from smallest to the big one"
-----very poor task or question. "Write the names from youngest to oldest" is what you want. 

PERSON            AGE        simplified
Joseph           (m-7)+5        m-2
Timothy          m-7            m-7
Mathew            m             m
