DETAILED EXPLANATION

\n" ); document.write( "
Look at \"x-8=highlight_red%28+4+%29\".
Moved these terms to the left \"highlight_green%28+-4+%29\"
It becomes \"x-8-highlight_green%28+4+%29=0\".
\n" ); document.write( "
Look at \"x-highlight_red%28+8+%29-highlight_red%28+4+%29=0\".
Added fractions or integers together
It becomes \"x%2Bhighlight_green%28+-12+%29=0\".
\n" ); document.write( "
Look at \"x%2Bhighlight_red%28+-12+%29=0\".
Removed extra sign in front of \"-12\"
It becomes \"x-highlight_green%28+12+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+x-12+%29=0\".
Solved linear equation \"highlight_red%28+x-12=0+%29\" equivalent to x-12 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
\n" ); document.write( "This is an equation! Solutions: x=12.
