You can put this solution on YOUR website!
x = pieces of silver for hat
\n" ); document.write( "y = pieces of silver for cape
\n" ); document.write( "z = pieces of silver for spyglass
\n" ); document.write( "---
\n" ); document.write( "x + y + z = 20
\n" ); document.write( "z = y + 5
\n" ); document.write( "y = x + 3
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y + z = 20
\n" ); document.write( "y - z = -5
\n" ); document.write( "x - y = -3
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:

\n" ); document.write( "x = pieces of silver for hat = 3
\n" ); document.write( "y = pieces of silver for cape = 6
\n" ); document.write( "z = pieces of silver for spyglass = 11
