Translation:

(NUMBER OF QUARTERS) 

plus 

(NUMBER OF NICKELS)

equals

or   N + Q = 25

Translation:

(5 cents times the NUMBER OF NICKELS) 

plus 

(25 cents times the NUMBER OF QUARTERS) 

equals

505 cents 

or  5N + 25Q = 505

Can you solve this system?  

{{{system(N+Q=25, 5N+25Q=505)}}}

If not post again asking how to.

Answer: 6 NICKELS and 19 QUARTERS.
