Question 994601
A collection of nickels, dimes, and quarters consist of 10 coins with a total of $1.10. If the number of dimes is equal to the number of nickels, find the number of each type of coins. Please help solve with steps, thanks. :)

let x=number of dimes and nickels
10-2x=number of quarters
.05x+.10x+.25(10-2x)=1.10
.05x+.10x+2.5-.5x=1.10
.35x=1.40
x=4
10-2x=10-8=2
number of dimes and nickels=4
10-2x=number of quarters=2
