Question 312883
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number of $2 coins.  Since there are 61 coins and bills, *[tex \Large 61\ -\ x] represents the number of $5 bills.


The value of *[tex \Large x] $2 coins is *[tex \Large 2x] dollars.  The value of *[tex \Large 61\ -\ x] $5 bills is *[tex \Large 5(61\ -\ x)] dollars.  We know there are $233 altogether, so:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ 5(61\ -\ x)\ =\ 233]


Just solve for *[tex \Large x] for the number of coins and subtract that from 61 for the number of bills.
