You can put this solution on YOUR website!
x = john age
\n" ); document.write( "y = sally age
\n" ); document.write( "z = mary age
\n" ); document.write( "---
\n" ); document.write( "x = 2y
\n" ); document.write( "y = 3z
\n" ); document.write( "x + y + z = 100
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - 2y = 0
\n" ); document.write( "y - 3z = 0
\n" ); document.write( "x + y + z = 100
\n" ); document.write( "---
