Question 479919
let x be the dimes, and let y be the nickels.

Then you know 1) x+y = 19 since there are 19 coins
and 2) the value of nickels times the number of nickels plus the value of a dime times the number of dimes should add up to 1.10, which is a fancy way of saying 0.10x+0.05y = 1.10

So with the two equations, you should be able to solve x and y
