You can put this solution on YOUR website!
Let quarters be y
\n" ); document.write( "Let nickels be x
\n" ); document.write( "Nickel value x 100 = 5
\n" ); document.write( "Quarter value x 100 = 25
\n" ); document.write( "total value x 100 = 725\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+y=57
\n" ); document.write( "y=57-x (subsition)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5x+25y=725
\n" ); document.write( "5x+25(57-x)=725
\n" ); document.write( "5x-25x+1425=725
\n" ); document.write( "-20x=-700
\n" ); document.write( "x=35\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y=57-35
\n" ); document.write( "y=22\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, he has 35 nickels and 22 quarters.
