DETAILED EXPLANATION

\n" ); document.write( "
Look at \"2%2Ax%2B72=highlight_red%28+4%2Ax+%29\".
Moved these terms to the left \"highlight_green%28+-4%2Ax+%29\"
It becomes \"2%2Ax%2B72-highlight_green%28+4%2Ax+%29=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+72+%29-4%2Ax=0\".
Moved \"72\" to the right of expression
It becomes \"2%2Ax-4%2Ax%2Bhighlight_green%28+72+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2Ax+%29-highlight_red%28+4%2Ax+%29%2B72=0\".
Eliminated similar terms \"highlight_red%28+2%2Ax+%29\",\"highlight_red%28+-4%2Ax+%29\" replacing them with \"highlight_green%28+%282-4%29%2Ax+%29\"
It becomes \"highlight_green%28+%282-4%29%2Ax+%29%2B72=0\".
\n" ); document.write( "
Look at \"%28highlight_red%28+2+%29-highlight_red%28+4+%29%29%2Ax%2B72=0\".
Added fractions or integers together
It becomes \"%28highlight_green%28+-2+%29%29%2Ax%2B72=0\".
\n" ); document.write( "
Look at \"%28highlight_red%28+-2+%29%29%2Ax%2B72=0\".
Removed extra sign in front of \"-2\"
It becomes \"%28-highlight_green%28+2+%29%29%2Ax%2B72=0\".
\n" ); document.write( "
Look at \"highlight_red%28+%28-highlight_red%28+2+%29%29%2Ax+%29%2B72=0\".
Remove unneeded parentheses around factor \"highlight_red%28+2+%29\"
It becomes \"-highlight_green%28+2+%29%2Ax%2B72=0\".
\n" ); document.write( "
Look at \"highlight_red%28+-2%2Ax%2B72+%29=0\".
Solved linear equation \"highlight_red%28+-2%2Ax%2B72=0+%29\" equivalent to -2*x+72 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
