Question 378750: A bank contained $1.75 in nickels and dimes. in all, there were 26 coins in the bank. how many of each are there? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let nickels be x
dimes be y
x+y = 26............1
..
5x+10y=175..........2
multiply (1) by -5
-5x-5y=-130
add this to (2)
10y-5y=175-130
5y=45
/5
y = 9 number of dimes
x= 26-9=17 number of nickels
