Very helpful, thank you very much! I used superposition and the formulae for summing opamps from your previous videos and got the same result :)

How v+=3v came
Can you explain that
1.03

[@ALLABOUTELECTRONICS]

1K resistor is common in the denominator. If you remove it, then we have 4 - V+ + (5 - V+) = V+
That means 9 - 2V+ = V+.
That means 3V+ = 9 or V+ = 3V
