Answer:
Accounting equation is stated as follows:
Assets = Liabilities + Stockholder's Equity
Transaction 1
Providing services will increase revenue, which will increase stockholder's equity. And since it is on account it will increase assets by the same amount = $39,000
Transaction 2
Cash received will increase cash in assets and will decrease accounts receivables in assets. Net effect = 0
Transaction 3
Purchase of equipment will increase equipment that is asset by $24,000 and further it is purchased through a note payable, it will increase liability with the same amount.
Transaction 4
This will decrease cash as paid in cash which will decrease assets, and further this will be expense for the period which will decrease the revenue and will decrease the stockholder's equity.
