2 x -5 y = -1 .............1
\n" ); document.write( "-3 y = -3 -1 x ---------2
\n" ); document.write( "/ -3 =
\n" ); document.write( " y = 1 + 0.33 x
\n" ); document.write( "Substitute y in (1)
\n" ); document.write( "2 x -5 ( 1 + 0.33 x ) = -1
\n" ); document.write( "2 x -5 + -1.67 x = -1
\n" ); document.write( "2 x -1.67 x = -1 5
\n" ); document.write( "0.33 x = 4
\n" ); document.write( "/ 0.33
\n" ); document.write( "x= 12
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "2 x -5 y = -1
\n" ); document.write( "2 * 12 -5 y = -1
\n" ); document.write( "24 -5 y = -1
\n" ); document.write( "-5 y = -25
\n" ); document.write( "/ -5
\n" ); document.write( "y= 5
