I've tried different ways to get the answer but they keep coming out wrong so can somebody tell me the formula for stock issuances?

Assets = Liabilities + Owners Equity

Owners Equity = Stock issuances + Retained Earnings

Retained Earnings = Net Income - Dividends

since you already know Assets and Liabilities, you can solve for Owners Equity. Now subtract Net Income from Owners Equity and you have your stock issuances.
