There are 52 coins in a purse. Some of them are quarters, and some are dimes.
\n" ); document.write( "The total value of all coins is $7.45. how many were quarters and how many were dimes?
\n" ); document.write( "------
\n" ); document.write( "Quantity Eq: d + q = 52 coins
\n" ); document.write( "Value Eq::: 10d+25q = 745 cents
\n" ); document.write( "------------------------------------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "10d + 10q = 520
\n" ); document.write( "10d + 25q = 745
\n" ); document.write( "----------------
\n" ); document.write( "Subtract and solve for \"q\":
\n" ); document.write( "15q = 225
\n" ); document.write( "q = 15 (# of quarters)
\n" ); document.write( "--------------------
\n" ); document.write( "Solve for \"d\":
\n" ); document.write( "d + q = 52
\n" ); document.write( "d + 15 = 52
\n" ); document.write( "d = 37 (# of dimes)
\n" ); document.write( "==========================
