numbers be x, y
\n" ); document.write( "11+x=3y
\n" ); document.write( "x-3y=-11..............1
\n" ); document.write( "x-9 = 1/2 y
\n" ); document.write( "2(x-9)=y
\n" ); document.write( "2x-18=y
\n" ); document.write( "y-2x=-18..............2
\n" ); document.write( "...\r
\n" ); document.write( "\n" ); document.write( "x-3y=-11 .............1
\n" ); document.write( "-2x+y =-18 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by 2
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "2x-6y =-22
\n" ); document.write( "-2x+y =-18
\n" ); document.write( "
\n" ); document.write( "Add the two equations

\n" ); document.write( "-5y=-40
\n" ); document.write( "
\n" ); document.write( "/-5
\n" ); document.write( "
\n" ); document.write( "y=8
\n" ); document.write( "Plug value of y in
\n" ); document.write( "x-3y=-11
\n" ); document.write( "x-24=-11
\n" ); document.write( "x=13
\n" ); document.write( "
