I offer the following solution from somewhat flimsy reasoning!

x 28 1
17 39 21
37 9 y

x and y replace the question marks.

Observe: 17+39+21=37+39+1.

Subtract each cell from the value in the central cell:

39-x 11 38
22 0 18
2 30 39-y

Observe: 2(30-11)=38.

Rotate the table. Apply the observation: (22-18)(39-y)=39-x, so 117=4y-x.

22+18=38+2=40; apply this to the rotated table: 39-x+39-y=40, 38=x+y so x=38-y.

117=4y-38+y, 5y=155, y=31, so x=7.

7 28 1
17 39 21
37 9 31
