@Python_Dv A = 18, B = -5, C = 3
How I solved it:
A ÷ C = 6 → A = 6C
A - C = 15 → 6C - C = 15 → 5C = 15 → C = 3
A = 6 × 3 = 18
A + B = 13 → 18 + B = 13 → B = -5
Old habits die hard 😅

@Python_Dv A equal 18
B equals -5
C equals 3
So A+B=13 will simply be 18+(-5)=13. As + X - equals minus.
So A➗C=6
And lastly A-C=15.

just need statements 2 and 3 to solve it. Statement 2 to make the hypothesis, statement 3 to test.
So what (simple) values of A divided by C would yield 6?
Obvious guess would be 18 / 3. Mkay, let´s test using statement 3. Is 18 - 3 = 15. Why yes it is.
Then by necessity A + B = 13, would give B a value of -5 So - A: 16, B: -5, C: 3

@Python_Dv 1. A+B=13
2. A/C=6 -> A=6C
3. A-C=15 -> 6C-C=15 -> 5C=15 -> C=3
A=6C -> A=18
A+B=13 -> B=13-A=13-18 -> B=-5
A=18; B=-5; C=3

@Python_Dv A=18 ; B=-5 ;C=3
A +B =13......................(1)
A÷C=6..........................(2)
A -C=15........................(3)
(2) : A÷C=6 ;--> A=6C
(3) : A -C=15; --> 6C-C=15 ;--> C=3; -->A=18
(1) : A +B =13; -->18+B=13; --> B=13-18=-5
Français

@Python_Dv A ÷ C = 6
A = 6 . C
A - C = 15
6C - C = 15
5C = 15
C = 3
A = 6 . C
A = 6 . 3
A = 18
A + B = 13
18 + B = 13
B = 13 - 18
B = -5
A = 18
B = -5
C = 3

@Python_Dv A+B=13
A÷C=6, A-C=15
A=6C
Therefore
6C-C=15
5C=15
C=15/5
C=3
And
A-3=15
A=15+3
A=18
Now
A+B=13
18+B=13
B=13-18
B=-5
Therefore
A=18, B=-5 and C=3
18+(-5)=13
18/3=6
18-3=15

@Python_Dv The real test is whether or not you believe this is a real IQ test.
If you believed this is a real IQ test: the results are in you have a low IQ
If you believed this is just a math question/click bait: then you have a high IQ
Thanks for coming to my TED Talk.
