Then the second is  and the third is .


The sum of the first and third is  or .
5 times that is 

This quantity is (meaning equals) 14 greater than 8 times the second.
8 times the second is , and 14 more than that is
, so we can write:





Add  to both sides




Add  to both sides




Multiply by 




Therefore the first number is , the second is  and the third is .
