From simulating the circuit, I know that Vo is 2V.

But I tried to write 3 KVL equations to solve for Vo manually just cannot get the right answer.

Help please!

 

I can't see your attachment. Can you?

Ok, I uploaded the picture to a different website. Can you see it now?

Can you upload pics to this website?

 

Now it is visible.

Where are your calculations?


Note that there is no current through R1, assuming an ideal op amp.

 

OK, i got it figured out.

In my first attempt I forgot factor in that no current flows through the 1.5k resistor. So therefore the same current flows through both 2k resistors. Then a couple KVL equations yield the correct answer.

Good for you!
