Hi there,
\n" ); document.write( "x-2y+2=0.
\n" ); document.write( "sort out to
\n" ); document.write( "x - 2y = -2....(1)
\n" ); document.write( "......
\n" ); document.write( "3x+y-8=0.
\n" ); document.write( "sort out to
\n" ); document.write( "3x + y = 8......(2)
\n" ); document.write( "........
\n" ); document.write( "x - 2y = -2....(1)
\n" ); document.write( "3x + y = 8......(2)
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "x - 2y = -2....(1)
\n" ); document.write( "6x + 2y = 16....(2)
\n" ); document.write( "Add (1) + (2)
\n" ); document.write( "7x = 14
\n" ); document.write( "x = 2
\n" ); document.write( "Substitute x = 2 into Eq(1)
\n" ); document.write( "x - 2y = -2
\n" ); document.write( "2 - 2y = -2
\n" ); document.write( "-2y = -2 - 2
\n" ); document.write( "-2y = -4
\n" ); document.write( "y = 2
\n" ); document.write( "Point of intersection of
\n" ); document.write( "l and m is (2,2)
\n" ); document.write( "Hope this helps:-)
\n" ); document.write( "
\n" );
