An equivalent voltage source in series with an equivalent im

An equivalent voltage source in series with an equivalent impedance means you should solve the problem using: the superposition theorem Millman\'s theorem Norton\'s theorem Thevenin\'s theorem

Solution

ANSWER :- Thevenin\'s theorem

An equivalent voltage source is connected in series with an equivalent resistance (or impedance) represents Thevenin\'s theorem and we should use Thevenin\'s theorem to solve it.
