\n" ); document.write( "The answer to them depends on the question asked. That could be one of several questions.
\n" ); document.write( "-----------
\n" ); document.write( "If you want to solve for x and y, you should say that, not \"what is the answer to...\"
\n" ); document.write( "---------
\n" ); document.write( "x=3y-1
\n" ); document.write( "x+2y=9
\n" ); document.write( "------
\n" ); document.write( "x+2y = 9
\n" ); document.write( "Sub eqn 1 for x
\n" ); document.write( "(3y-1) + 2y = 9
\n" ); document.write( "5y - 1 = 9
\n" ); document.write( "5y = 10
\n" ); document.write( "y = 2
\n" ); document.write( "-------
\n" ); document.write( "x = 3y-1
\n" ); document.write( "x = 5
