Finding current in a parallel circuit

[rms5643]

Homework Statement

Determine IL in the circuit in the Figure.

V1 = ?
Ix = ?
IL = ?
3*Ix current source pointing downwards
7mA current source pointing upwards
7mA current source pointing downwards
7kOhm resistor
1kOhm resistor

Homework Equations

Ohm's law, KCL

The Attempt at a Solution

The hint to the problem told me to: "Write a KCL equation at the top node and express any control variables for dependent sources in terms of the unknown node voltage."

So, I wrote the equation and I got:

V1/5kΩ+3(V1/5kΩ)+V1/7kΩ+V1/1kΩ=0

I'm not quite sure where to go from here or how this form would be useful to me. Any pointers on where I should go from here? Thank you

It looks like V1=0. Nothing else solves that equation.
