Dual power supply for Op Amp
The µA741 can be used in single voltage applications.
The 741 is pretty lousy as far as op-amps go.
There are better op-amps that work better on single voltage supplies.
You cannot power an op-amp from a voltage divider (insane things like two 1 Ohm resistors excluded.)


What you need to do is to look up single voltage operation for op-amps, and see what you need to do.  Hint: It does involve a voltage divider, but not powering the amp.

Here is an example of a 741 running on a single voltage:
