You can put this solution on YOUR website!
3x-11y=9 multply by 3 & add.
\n" ); document.write( "-9x+33y=18
\n" ); document.write( "9x-33y=27
\n" ); document.write( "-------------------
\n" ); document.write( "0x+0y=45
\n" ); document.write( "3x-11y=9
\n" ); document.write( "-11y=-3x=9
\n" ); document.write( "These two lines are parallel line.
\n" ); document.write( "Thus there is no solution for x & y.
\n" ); document.write( "y=-3x/-11+8/-11
\n" ); document.write( "y=3x/11-8/11 (red line)
