Can anyone help me figure out how to answer question 1?

Simplify first :

1) R5 and R6 are in series, so what would the equivalent R in place of them be ?

2) The equivalent R from 2) is in parallel with R4, so whats that new equivalent ?

3) You now have a simple V divider to compute V4......

Regards, Dana.

Once you're done 1 and 2, redraw the schematic in a more conventional manner. Start with the current source to the left, with any resistors directly in parallel with it. Extend the + and - (GND) rails to the right, and then fill in the remaining resistors and equivalent resistors. The + terminal connects to three resistors in the original schematic, so there should be three branches in parallel between the + and - rails.

Once you do that, you can collapse the entire network to a single equivalent resistor across the current source. This gives the current source a terminal voltage. With this voltage and Ohm's Law, you can work out the current through, and voltage across, each resistor.
