How would I find what the revenue is if only given Dividends,Expenses,Stockholders equity during the year?

Please do not tag onto other people's threads - always start your own for your question. I've moved your post to its own thread.

Stockholder equity is affect by issuance of stock, net income and dividends:
Beginning Balance
+ Any new stock issuance
+ Net Income**
- Dividends
= Ending Balance

**Since net income comes from revenues - expenses, we can also look at it like:
Beginning Balance
+ new issuance of stock
+ revenue
- expenses
- dividens
= ending balance

Looks like you have no issuances of stock so that can be thrown out. With the rest, plug in what you have and find the missing number.
