DETAILED EXPLANATION

\n" ); document.write( "
Look at \"28=highlight_red%28+3%2Am+%29-highlight_red%28+7%2Am+%29\".
Eliminated similar terms \"highlight_red%28+3%2Am+%29\",\"highlight_red%28+-7%2Am+%29\" replacing them with \"highlight_green%28+%283-7%29%2Am+%29\"
It becomes \"28=highlight_green%28+%283-7%29%2Am+%29\".
\n" ); document.write( "
Look at \"28=%28highlight_red%28+3+%29-highlight_red%28+7+%29%29%2Am\".
Added fractions or integers together
It becomes \"28=%28highlight_green%28+-4+%29%29%2Am\".
\n" ); document.write( "
Look at \"28=%28highlight_red%28+-4+%29%29%2Am\".
Removed extra sign in front of \"-4\"
It becomes \"28=%28-highlight_green%28+4+%29%29%2Am\".
\n" ); document.write( "
Look at \"28=highlight_red%28+%28-highlight_red%28+4+%29%29%2Am+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+4+%29\"
It becomes \"28=-highlight_green%28+4+%29%2Am\".
\n" ); document.write( "
Look at \"28=highlight_red%28+-4%2Am+%29\".
Moved these terms to the left \"highlight_green%28+4%2Am+%29\"
It becomes \"28%2Bhighlight_green%28+4%2Am+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+28+%29%2B4%2Am=0\".
Moved \"28\" to the right of expression
It becomes \"4%2Am%2Bhighlight_green%28+28+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+4%2Am%2B28+%29=0\".
Solved linear equation \"highlight_red%28+4%2Am%2B28=0+%29\" equivalent to 4*m+28 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
