DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+7%2Ax+%29-highlight_red%28+5%2Ax+%29%2B15=x%2B8\".
Eliminated similar terms \"highlight_red%28+7%2Ax+%29\",\"highlight_red%28+-5%2Ax+%29\" replacing them with \"highlight_green%28+%287-5%29%2Ax+%29\"
It becomes \"highlight_green%28+%287-5%29%2Ax+%29%2B15=x%2B8\".
\n" ); document.write( "
Look at \"%28highlight_red%28+7+%29-highlight_red%28+5+%29%29%2Ax%2B15=x%2B8\".
Added fractions or integers together
It becomes \"%28highlight_green%28+2+%29%29%2Ax%2B15=x%2B8\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+2+%29%29%2Ax+%29%2B15=x%2B8\".
Remove unneeded parentheses around factor \"highlight_red%28+2+%29\"
It becomes \"highlight_green%28+2+%29%2Ax%2B15=x%2B8\".
\n" ); document.write( "
Look at \"2%2Ax%2B15=highlight_red%28+x%2B8+%29\".
Moved these terms to the left \"highlight_green%28+-x+%29\",\"highlight_green%28+-8+%29\"
It becomes \"2%2Ax%2B15-highlight_green%28+x+%29-highlight_green%28+8+%29=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+15+%29-x-highlight_red%28+8+%29=0\".
Added fractions or integers together
It becomes \"2%2Ax%2Bhighlight_green%28+7+%29-x=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+7+%29-x=0\".
Moved \"7\" to the right of expression
It becomes \"2%2Ax-x%2Bhighlight_green%28+7+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2Ax+%29-highlight_red%28+x+%29%2B7=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%2B7=0\".
\n" ); document.write( "
Look at \"highlight_red%28+%282-1%29+%29%2Ax%2B7=0\".
Remove extraneous '1' from product \"highlight_red%28+%282-1%29+%29\"
It becomes \"x%2B7=0\".
\n" ); document.write( "
Look at \"highlight_red%28+x%2B7+%29=0\".
Solved linear equation \"highlight_red%28+x%2B7=0+%29\" equivalent to x+7 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
