You can find the numerical part of the answer because it is the same on the right side.
For example:
¹ <<==== Regrouped
89
+
67
---------
146 <<=== I had to press space so I could position it.
So that also happens in subtraction, the left side can be found by doing the same steps in the right column.
For example:
67
- <<=== this time there was no regrouping
12
-------
55
One equivalent fraction for 4/21 could be 8/42.
The page numbers must have a difference of one, so:
n * (n+1) = 182
n^2 + n -182 =0
Solving by the quadratic formula we see n = 13 and n+1 = 14
