>Find the current through 25V cell & power supplied by
20V cell in the figure shown.

I know how to solve this question by writting KVL equation for every loop ,then solve these equation. But doing it , it is getting to long . I want to know if there is another method to solve this .

eg The voltage across the 10$\Omega$ resistor must be 30V (because 30-5=25) so the current is +3A (down).
