i attached the problem.
I am unsure how to solve this problem. I applied KVL and got 15-1I-2vx-vx-2I=0. Where I is the current in the circuit. From that equation I have 2 unknowns, so I obviously have to find I.
To find I I'd have to find Req, but I don't know how the resistors are arranged. the 2 ohm and 5ohm resistors are in series giving an equivalent R=7ohms. Is the 1ohm resistor in parallel with the combination R=7ohm?
