You can put this solution on YOUR website!
x = nickels
\n" ); document.write( "y = dimes
\n" ); document.write( "z = quarters
\n" ); document.write( "---
\n" ); document.write( "x + y + z = 21
\n" ); document.write( "5x + 10y + 25z = 335
\n" ); document.write( "z = y + 4
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y + z = 21
\n" ); document.write( "5x + 10y + 25z = 335
\n" ); document.write( "-y + z = 4
