Non inverting op amp scale and offset

Hey people!

The problem is simple: sensor is sending voltages ranging +1.6V to +10V but other device has to read it as 0V to +10V
I've learned that op amp is perfect to make a little converter.

I managed to use TLV2371IP op amp (non inverting setup) to scale voltage. Now I've got range +1.6V / +10V at input and +2V / +12V at the output.

I use 0 / +12 to the rails

I wasn't smart enough to get offset so my range at output would become 0 / +10.

So I hope people smarter than me could help me? I've googled and tried many circuits out there, but non of them work out.

Below is the LTspice simulation of one approach:
The output (Yellow trace) goes form 62mV to 10.1V for an input (Green trace) of 1.6V to 10V.
