## Homework Statement

Find [itex]V_x[/itex] in the circuit.

## Homework Equations

[itex]\displaystyle{\sum V_i=0}[/itex]

## The Attempt at a Solution

I tried to add all of the voltages and label the 2 ohm res V1 and 1 ohm res V2.

Then I did:

[itex]V_x+V_1-15+V_2+2V_x=0[/itex]

[itex]3V_x+V_1+V_2=15[/itex]

but then I couldn't find any other equations that will aid me in solving this.

I'm not really sure if I really need the V1 and V2.

The circuit doesn't give you the current either, so I don't know why resistance would help.

Thanks.
