output node, to the ground node.

And that can be also determined by the voltage

drop across the one kilohm resistor to the voltage drop

across the Other 1k ohm resistor in the center bottom of our circuit.

We add these two up, and we can get Vout.

So, Vout = 1k, for

this first voltage drop,

I2- I3 And

for the second voltage drop is going to be 1K,

I1- I3 that's equal to V out.

So if we have I1 and I2 and I3 then we

can find V out So if we solve this then we

end up with I1 equal to 5 milliamps and

I2 equal to -7 milliamps,

we have I3 already So, if we use these and

solve for Vo, than we get a Vo=2V.
