DETAILED EXPLANATION

\n" ); document.write( "
Look at \"2%2Ax%2B1=-highlight_red%28+4+%29%2B7%2Ax\".
Moved \"-4\" to the right of expression
It becomes \"2%2Ax%2B1=7%2Ax-highlight_green%28+4+%29\".
\n" ); document.write( "
Look at \"2%2Ax%2B1=highlight_red%28+7%2Ax-4+%29\".
Moved these terms to the left \"highlight_green%28+-7%2Ax+%29\",\"highlight_green%28+4+%29\"
It becomes \"2%2Ax%2B1-highlight_green%28+7%2Ax+%29%2Bhighlight_green%28+4+%29=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+1+%29-7%2Ax%2Bhighlight_red%28+4+%29=0\".
Added fractions or integers together
It becomes \"2%2Ax%2Bhighlight_green%28+5+%29-7%2Ax=0\".
\n" ); document.write( "
Look at \"2%2Ax%2Bhighlight_red%28+5+%29-7%2Ax=0\".
Moved \"5\" to the right of expression
It becomes \"2%2Ax-7%2Ax%2Bhighlight_green%28+5+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2Ax+%29-highlight_red%28+7%2Ax+%29%2B5=0\".
Eliminated similar terms \"highlight_red%28+2%2Ax+%29\",\"highlight_red%28+-7%2Ax+%29\" replacing them with \"highlight_green%28+%282-7%29%2Ax+%29\"
It becomes \"highlight_green%28+%282-7%29%2Ax+%29%2B5=0\".
\n" ); document.write( "
Look at \"%28highlight_red%28+2+%29-highlight_red%28+7+%29%29%2Ax%2B5=0\".
Added fractions or integers together
It becomes \"%28highlight_green%28+-5+%29%29%2Ax%2B5=0\".
\n" ); document.write( "
Look at \"%28highlight_red%28+-5+%29%29%2Ax%2B5=0\".
Removed extra sign in front of \"-5\"
It becomes \"%28-highlight_green%28+5+%29%29%2Ax%2B5=0\".
\n" ); document.write( "
Look at \"highlight_red%28+%28-highlight_red%28+5+%29%29%2Ax+%29%2B5=0\".
Remove unneeded parentheses around factor \"highlight_red%28+5+%29\"
It becomes \"-highlight_green%28+5+%29%2Ax%2B5=0\".
\n" ); document.write( "
Look at \"highlight_red%28+-5%2Ax%2B5+%29=0\".
Solved linear equation \"highlight_red%28+-5%2Ax%2B5=0+%29\" equivalent to -5*x+5 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
\n" ); document.write( "This is an equation! Solutions: x=1.
