solve the following system of equations.\r
\n" ); document.write( "\n" ); document.write( "x+7y=9
\n" ); document.write( "x=4-7y --> x+7y = 4
\n" ); document.write( "----------------
\n" ); document.write( "x+7y = 9
\n" ); document.write( "x+7y = 4
\n" ); document.write( "--------------- Subtract
\n" ); document.write( "0 = 5
\n" ); document.write( "---
\n" ); document.write( "It's inconsistent ---> no solution
\n" ); document.write( "If you graph the equations, you get parallel lines.
\n" ); document.write( "No intersection, no solution
\n" ); document.write( "
\n" ); document.write( "
\n" );
