Hi,

Why did you use the formula for Non-Inverting?

I think the circuit is Inverting because the supply is in the Inverting terminal. And the formula for inverting is Vo= -(Rf/Ri)*Vi.

Please clarify this.

vin/R2 + vin-vo/R1.

Vlt = -Vo(max)(R2/R1+R2).

Then,
Vlt = -13(47k/200k+47).

= -2.47V.

Vout=-Vin(R2/R1+1)
then,
Vout=-2*(47k/200k+1)
=-2*(1.235)
=-2.47V
