DETAILED EXPLANATION
\n" );
document.write( "
Look at \"3%2Ax-5-2%2Ax-highlight_red%28+%288-9%29+%29=0\".
 Remove unneeded parentheses around terms \"highlight_red%28+-8+%29\",\"highlight_red%28+9+%29\"
It becomes \"3%2Ax-5-2%2Ax-highlight_green%28+8+%29%2Bhighlight_green%28+9+%29=0\".
\n" );
document.write( "
Look at \"3%2Ax-highlight_red%28+5+%29-2%2Ax-highlight_red%28+8+%29%2Bhighlight_red%28+9+%29=0\".
 Added fractions or integers together 
It becomes \"3%2Ax%2Bhighlight_green%28+-4+%29-2%2Ax=0\".
\n" );
document.write( "
Look at \"3%2Ax%2Bhighlight_red%28+-4+%29-2%2Ax=0\".
 Moved \"-4\" to the right of expression 
It becomes \"3%2Ax-2%2Ax%2Bhighlight_green%28+-4+%29=0\".
\n" );
document.write( "
Look at \"3%2Ax-2%2Ax%2Bhighlight_red%28+-4+%29=0\".
 Removed extra sign in front of \"-4\"
It becomes \"3%2Ax-2%2Ax-highlight_green%28+4+%29=0\".
\n" );
document.write( "
Look at \"highlight_red%28+3%2Ax+%29-highlight_red%28+2%2Ax+%29-4=0\".
 Eliminated similar terms \"highlight_red%28+3%2Ax+%29\",\"highlight_red%28+-2%2Ax+%29\"  replacing them with  \"highlight_green%28+%283-2%29%2Ax+%29\"
It becomes \"highlight_green%28+%283-2%29%2Ax+%29-4=0\".
\n" );
document.write( "
Look at \"highlight_red%28+%283-2%29+%29%2Ax-4=0\".
 Remove extraneous '1' from product \"highlight_red%28+%283-2%29+%29\"
It becomes \"x-4=0\".
\n" );
document.write( "
Look at \"highlight_red%28+x-4+%29=0\".
 Solved linear equation \"highlight_red%28+x-4=0+%29\" equivalent to  x-4  =0 
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
