IF
7 - 3 = 10124
6 + 3 = 3279
5 - 2 = 763
11+ 2 = 92613

Then,
15 - 3 =?

7 - 3 = 10124
6 + 3 = 3279
5 - 2 = 763
11+ 2 = 92613

Then,
15 - 3 = 183612
EXPLANATION :
A + B = (A -- B) [B(A + B)] (A + B)
C -- D = (C + D) [ D(C -- D)] (C -- D)

What an interesting puzzle!

So if 5 - 2 = 763, then 763 must equal 3. So if 7 - 3 = 10,124, then 7 must be 10,124 + 763 = 10,887.
6 is 3279 - 763 = 2516.

So far, we have...

7 = 10,887
3 = 763
6 = 2516

If 7 - 3 = 10,124, then that must mean that 4 = 10,124.
7 + 4 = 11, so 10,124 + 10,887 = 11 = 21,011.
2 = 92,613 - 21,011, so 2 = 71,602

Final list of numbers:

2 = 71,602
3 = 763
4 = 10,124
6 = 2516
7 = 10,887
11 = 21,011

7 + 6 + 2 = 15, so 15 = 10,887 + 2,516 + 71,602 = 85,005
85,005 - 763 = 84,242

The final answer is 84,242.

7 + 3 = 10
7 - 3 = 4
4 x 3 = 12

Rearrange to match the given of 10124.
......................................…

If 15 + 3 = 18

and

15 - 3 = 12,

and

12 x 3 = 36

then, rerarranging as above yields

15 - 3 = 183612
...

i guess you didn't pay attention in school.
7-3 = 4
6+3 =9
5-2 = 3
11+2 = 13
and 15 - 3 = 12
