2x-3y = 13 .............1
\n" ); document.write( "
\n" ); document.write( "4y=8-x ---------2
\n" ); document.write( "/4
\n" ); document.write( "y=2-0.25x
\n" ); document.write( "Plug the value of y in (1)
\n" ); document.write( "2x-3(2-0.25x)=13
\n" ); document.write( "2x-6+0.75x=13
\n" ); document.write( "2x+0.75 x=13+6
\n" ); document.write( "2.75 x = 19
\n" ); document.write( "/ 2.75
\n" ); document.write( "x= 6.91
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "2x-3y=13
\n" ); document.write( "2*6.91-3y=13
\n" ); document.write( "13.82 -3y=13
\n" ); document.write( "-3y=-0.82
\n" ); document.write( "/-3
\n" ); document.write( "y=0.27
\n" ); document.write( " \n" ); document.write( "

\n" );
