DETAILED EXPLANATION

\n" ); document.write( "
Look at \"2%2Ax=highlight_red%28+x%2B3+%29\".
Moved these terms to the left \"highlight_green%28+-x+%29\",\"highlight_green%28+-3+%29\"
It becomes \"2%2Ax-highlight_green%28+x+%29-highlight_green%28+3+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2Ax+%29-highlight_red%28+x+%29-3=0\".
Eliminated similar terms \"highlight_red%28+2%2Ax+%29\",\"highlight_red%28+-x+%29\" replacing them with \"highlight_green%28+%282-1%29%2Ax+%29\"
It becomes \"highlight_green%28+%282-1%29%2Ax+%29-3=0\".
\n" ); document.write( "
Look at \"highlight_red%28+%282-1%29+%29%2Ax-3=0\".
Remove extraneous '1' from product \"highlight_red%28+%282-1%29+%29\"
It becomes \"x-3=0\".
\n" ); document.write( "
Look at \"highlight_red%28+x-3+%29=0\".
Solved linear equation \"highlight_red%28+x-3=0+%29\" equivalent to x-3 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
\n" ); document.write( "This is an equation! Solutions: x=3.
