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.
