3x+2y=5 .............1
\n" ); document.write( "9y=4+5x ---------2
\n" ); document.write( "/9 =
\n" ); document.write( "y=0.44+0.56x
\n" ); document.write( "Plug the value of y in (1)
\n" ); document.write( "3x+2(0.44+0.56x)
\n" ); document.write( "3x+0.89 +1.11x=5
\n" ); document.write( "3x+1.11 x=5-0.89
\n" ); document.write( "4.11x=4.11
\n" ); document.write( "/4.11
\n" ); document.write( "x=1
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "3x+2y=5
