Hi Welcome to Openstudy!!!

let x be the number of nickels
    y  be the the number of dimes 

total amount of money is given by the equation

0.5 x + 0.10 y = 0.90 

total number of coins is given by the equation

x + y = ??? seems like your question is incomplete

@Legends can you show us your solution?

yes sorry ok so we automatically take away 30 cents from 90 because we know that there is 3 more dimes than nickles. So that leaves us with 60 cents.
