Two op amps from a single input voltage
First, get a different op anp. The 741 is designed to work from +/- 15 volts, and is not specified for anything else. As an example, at +/- 15 volts the output swing for a 2k load is only guaranteed to be +/- 10 volts. So if 5 volts is the difference between the supply and the maximum load output, for a +/- 5 volts supply the output may only provide +/- 0 volts. That said, the following should work if you use the right op amps

Also, it assumes your -5 is quiet, stable and accurate.
