Best ResponseYou've already chosen the best response.0let x = no. of nickels y = no. of dimes x + y = 30 5(cents)x + 10(cents)y = 240 multiply the first equation by 5 5x  5y = 150 5x + 10y = 240 5y = 90 y = 19 There are 19 dimes and 11 nickels. I remembered how to do it :D It seems i made a mistake in my solution before that's why I can't solve it.
