I agree that Part (b) on the second one is real tricky, since the directions of I1 and I2 are undefined.

Since you have spent hours trying to solve these, you should be able to post your best attempt for us to use as a starting point. It is, after all, YOUR homework.

Hint: The two voltages (V1 and V2) in the first problem and two of the voltages (V1 and Vb) in the second problem can be written down by inspection, provided you understand what voltage is.

These are not elementary arrangements, but there are several solution methods available.

You must have studied some further methods than series/parallel combinations to have been set these.

So let us start by you telling us which ones and showing us what you have achieved so far.
