You can put this solution on YOUR website!
x = david mass
\n" ); document.write( "y = john mass
\n" ); document.write( "z = paul mass
\n" ); document.write( "---
\n" ); document.write( "x = y - 5
\n" ); document.write( "y = z - 8
\n" ); document.write( "x + y + z = 197
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = -5
\n" ); document.write( "y - z = -8
\n" ); document.write( "x + y + z = 197
\n" ); document.write( "---
