7. I mean: A.

My first idea was that with 3 equations and 4 variables, you could easily fit the center value as a linear combination of any 3 corners. You could even make fit all 4 equations with any value at the question mark. I discarded the idea as, too easy.
And yet...

1x8+2x3+3x7+4x1 = 39
1x2+2x6+3x4+4x5 = 46
1x9+2x6+3x1+4x2 = 32
1x4+2x3+3x7+4x3 = 43
