You can put this solution on YOUR website!
x = kg of $14 bars
\n" ); document.write( "y = kg of $8 bars
\n" ); document.write( "---
\n" ); document.write( "x + y = 42
\n" ); document.write( "14x + 8y = 10*42
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
