How to solve this problem : (-7) = e3+14? and what's the answer?

If you are trying to find e, then its - 7

You are going to want to isolate the variable (e). to do this, you must first subtract 14 from both sides leaving you with - 21=e3. next, to find what e equals, you have to divide both sides by 3 because of the coefficient on the variable, which is 3. you should end with the answer of - 7=e.
