Hi there,
\n" ); document.write( "x - y = 1.......(1)
\n" ); document.write( "x + 2y = 7......(2)
\n" ); document.write( "Subtract (1) from (2)
\n" ); document.write( "-3y = -6
\n" ); document.write( "y = 2
\n" ); document.write( "Substitute y = 2 into
\n" ); document.write( "x - y = 1
\n" ); document.write( "x - 2 = 1
\n" ); document.write( "x = 1 + 2
\n" ); document.write( "x = 3
\n" ); document.write( "x = 3, y = 2.
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
