Engineering What are the voltage ratios in an op amp circuit?

[gfd43tg]

I have to find both of the voltage ratios. This is just ugly algebra. Here is what I came up with, and was wondering if I was correct.
Thanks

If the opamps are ideal, they have infinite gain and their inputs draw no current.

You correctly saw that this means R2 is not involved in the analysis, but you failed to notice that R5 is not involved for the same reasons.

You'll need to redo your work with R5 replaced with a wire; no R5, in other words.

Is it really that easy?

Edit: Wait a minute, I remember the professor saying to never do KCL at the output of an op-amp, I will redo this.

Ok here is my next attempt hopefully it's right

I found an algebra error in my Vout/Vin and fixed it

You're good to go!
