3. The attempt at a solution

I'm kind of confused as to how to approach this question as a whole because I'm getting put off from the two voltage sources.

I was thinking that maybe I could use mesh current analysis so then I'd get:

-10 + 1200([itex]i_{1}[/itex]) + 3300([itex]i_{1}[/itex] - [itex]i_{2}[/itex]) + 12 = 0

where [itex]i_{2}[/itex] = 0 since it's within an open circuit, so then

1200([itex]i_{1}[/itex]) + 3300([itex]i_{1}[/itex]) = -2

4500([itex]i_{1}[/itex]) = -2

[itex]i_{1}[/itex] = [itex]\frac{-2}{4500}[/itex] A

Then,

[itex]V_{oc}[/itex] = [itex]\frac{-2}{4500}[/itex] * 3300

[itex]V_{oc}[/itex] = 1.5 V

but that doesn't sound right, so I'm not sure how else to approach it. Thanks for help in advance!
