You want to multiply the value times the number of coins to get the total dollar amount; that is, I think you've switched the answers.  

What you have typed is:
10 times the number of dimes plus 25 times the number of quarters equals 22.
You want the number of dimes plus the number of quarters to equal 22.

Make sense?
