You can put this solution on YOUR website!
4 x -1 y = 12 .............1
\n" ); document.write( "Total value
\n" ); document.write( "-8 x + 2 y = -24 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 2
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "8 x -2 y = 24
\n" ); document.write( "-8 x + 2 y = -24
\n" ); document.write( "Add the two equations
\n" ); document.write( "0 x = 0 \r
\n" ); document.write( "\n" ); document.write( "this is absurd\r
\n" ); document.write( "\n" ); document.write( "Both the equations are of the same line.
\n" ); document.write( "Hence there are infinite solutions \n" ); document.write( "

\n" );
