You can put this solution on YOUR website!
-1 x + 3 y = 6 .............1
\n" ); document.write( "1 y = 2 + 0.33 x ---------2
\n" ); document.write( "/ 1 =
\n" ); document.write( " y = 2 + 0.33 x
\n" ); document.write( "Substitute y in (1)
\n" ); document.write( "-1 x + 3 ( 2 + 0.33 x ) = 6
\n" ); document.write( "-1 x + 6 + 1 x = 6
\n" ); document.write( "-1 x + 1 x = 6 -6
\n" ); document.write( "0 x = 0
\n" ); document.write( "the lines are coinciding with each other. there are innumerable solutions.\r
