Question 656636
<font face="Times New Roman" size="+2">


You were good to go at *[tex \LARGE 4x\ =\ 36\ -\ 5x].  Then if you subtracted 4 from both sides you would have had *[tex \LARGE 4x\ -\ 4\ =\ 32\ -\ 5x] which is just a bigger mess to clean up.  What you actually did was subtract *[tex \LARGE 4x] from both sides, leaving you with *[tex \LARGE 0\ =\ 36\ -\ 9x] and causing you to have to do another step...bad form.


Add *[tex \LARGE 5x] to both sides, then multiply by *[tex \LARGE \frac{1}{9}]


And give me your address so that I can come wash your mouth out with soap if you ever say the word "subtract" again as long as you live.  NEVER subtract, instead, add the opposite.  Same thing with divide.  NEVER divide; multiply by the reciprocal.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
