DETAILED EXPLANATION

\n" ); document.write( "
Look at \"45=-highlight_red%28+%28highlight_red%28+1%2F4+%29%29%2Ad+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+1+%29\",\"highlight_red%28+1%2F4+%29\"
It becomes \"45=-highlight_green%28+1+%29%2Fhighlight_green%28+4+%29%2Ad\".
\n" ); document.write( "
Look at \"45=-highlight_red%28+1+%29%2F4%2Ad\".
Remove extraneous '1' from product \"highlight_red%28+1+%29\"
It becomes \"45=-d%2F4\".
\n" ); document.write( "
Look at \"45=highlight_red%28+-d%2F4+%29\".
Moved these terms to the left \"highlight_green%28+d%2F4+%29\"
It becomes \"45%2Bhighlight_green%28+d%2F4+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+45+%29%2Bd%2F4=0\".
Moved \"45\" to the right of expression
It becomes \"d%2F4%2Bhighlight_green%28+45+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+d%2F4%2B45+%29=0\".
Solved linear equation \"highlight_red%28+d%2F4%2B45=0+%29\" equivalent to 0.25*d+45 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
\n" ); document.write( "This is an equation! Solutions: d=-180.
