Let x be the number of nickels
Let 23-x be the number of dimes
---------------------------------
0.05x+(23-x)0.1=1.65
0.05x+2.3-0.1x=1.65
0.05x-0.1x=1.65-2.3
-0.05x=-0.65
x=13
-----------------------------------
23 coins-13nickels=10dimes
-------------------------------------
Therefore, Andres has 13 nickels and 10 dimes
