Question 304361: Here is a word problem. Write a system of two equations in two unknowns and solve by the method of your choice. Don�t forget to show the methodology. Irving has 35 coins, consisting of only dimes and nickels. If the value of his coins is $3.30, how many nickels and dimes does he have?

Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
let the number of dimes be x
& the number of nickels be y
x+y=35
value of the coins
10x+5y=330 cents
10(x+y)-(10x+5y) = 10*35 -330
10x+10y-10x-5y=350-330
5y=20
y=4 the number of nickels
35-4 =31 the number of dimes
