# operational amplifiers, voltage divider

Could someone please tell me what is the value of Ux? How can i calculate it?

is Ux = (U1 - U2) * R2/(R1+R2) correct?

• Your question doesn't really have anything to do with operational amplifiers. Were you aware of this? Commented Feb 5 at 16:03
• You need to show your work so far. This isn't a homework service.

• For homework types of questions we expect you to show that you have made a substantial effort to solve the problem yourself. Show us all of your work and then ask a specific question. Commented Feb 5 at 16:23
• to solve this problem i know that i need to use the voltage divider formula, but since there are two voltage sources i am confused how should i apply the formula , i am sorry i am still in school, not a great researcher like yourself. just asked for a simple explanation, got so much backlash. thanks anyways!

• @Andyaka, you have to know what the ideal properties of the op amp inputs are to solve the problem. Commented Feb 5 at 16:31
