Put them both into the standard form
\n" ); document.write( "which looks like:
\n" ); document.write( " $\"+ax+%2B+by+=+c+\"$
\n" ); document.write( "---------------
\n" ); document.write( " $\"+y+-+4+=+3x+\"$
\n" ); document.write( "Subtract $\"+y+\"$ from both sides
\n" ); document.write( " $\"+-4+=+3x+-+y+\"$
\n" ); document.write( "Write it the other way around
\n" ); document.write( " $\"+3x+-+y+=+-4+\"$
\n" ); document.write( "---------------
\n" ); document.write( " $\"+2y-6x=8+\"$
\n" ); document.write( "Just write it this way:
\n" ); document.write( " $\"+-6x+%2B+2y+=+8+\"$
\n" ); document.write( "Now divide both sides by $\"+2+\"$
\n" ); document.write( " $\"+-3x+%2B+y+=+4+\"$
\n" ); document.write( "Multiply both sides by $\"+-1+\"$
\n" ); document.write( " $\"+3x+-+y+=+-4+\"$
\n" ); document.write( "---------------
\n" ); document.write( "They are both the same equation, so neither is the
\n" ); document.write( "correct choice
\n" ); document.write( " \n" ); document.write( "

\n" );
