5 x -4 y = 5 .............1
\n" ); document.write( "1 y = 11 -1 x ---------2
\n" ); document.write( "/ 1 =
\n" ); document.write( " y = 11 -1 x
\n" ); document.write( "Substitute y in (1)
\n" ); document.write( "5 x -4 ( 11 -1 x ) =
\n" ); document.write( "5 x -44 + 4 x = 5
\n" ); document.write( "5 x + 4 x = 5 44
\n" ); document.write( "9 x = 49
\n" ); document.write( "/ 9
\n" ); document.write( "x= 49/9
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "5 x -4 y = 5
\n" ); document.write( "5 * 49/9 -4 y = 5
\n" ); document.write( "245/9 -4 y = 5
\n" ); document.write( "-4 y = 5-(249/9)
\n" ); document.write( "-4y=-204/9
\n" ); document.write( "/ -4
\n" ); document.write( "y= 51/9
