The problem is:
\n" ); document.write( "y=x-3
\n" ); document.write( "x+y=5
\n" ); document.write( "--------
\n" ); document.write( "You are told that y = x-3 so substitute that into the 2nd equation
\n" ); document.write( "to get:
\n" ); document.write( "x+(x-3) = 5
\n" ); document.write( "2x-3=5
\n" ); document.write( "2x = 8
\n" ); document.write( "x = 4
\n" ); document.write( "-----------
\n" ); document.write( "Now, since y = x-3, substitute to get:
\n" ); document.write( "y = 4-3 = 1
\n" ); document.write( "----------------
\n" ); document.write( "Solution: (4,1)
\n" ); document.write( "==================
