You can put this solution on YOUR website!
Add the two equations together.
\n" ); document.write( "1. $\"3x-4y=9\"$
\n" ); document.write( "2. $\"-3x%2B4y=12+\"$
\n" ); document.write( " $\"3x-4y-3x%2B4y=9%2B12\"$
\n" ); document.write( " $\"0=21\"$
\n" ); document.write( "This is an inconsistent system.
\n" ); document.write( "The lines are parallel and never meet.
\n" ); document.write( "There is no solution.
