I am not certain what you want.
Try this:
Scale = [920 1; 850 1] \ [960; 882]
NewValue = [920 1; 850 1] * Scale
producing:
Scale =
1.114285714285713
-65.142857142856428
NewValue =
960
882
This simply does a linear regression (of sorts) between the old value and the new value.

You changed the numbers in your Question, so just change the numbers in the ‘Scale’ calculation in my Answer:
Scale = [920 1; 850 1] \ [960; 870]
NewValue = [920 1; 850 1] * Scale
producing:
Scale =
1.28571428571428
-222.857142857142
NewValue =
960
870
