All of them are wrong except number 12. The top left is 7, the top right is 26, the bottom left is 4. And a little hint, do what's in the parentheses first. Hope I helped!!
31+(24-19)-8*4
31+ 5-8*4
31+5-32
37-32=5
Number 9 is wrong. the correct answer is 5.

10. 48 -9 * 2-4
48 - 18 -4
30-4= 26
Number 10 is wrong , the correct answer is 26.

11. 56÷ ( 10-5+3*3)
10-5+9
5+9 =14

56÷ 14 =4
Number 11 is wrong. the correct answer is 4.

12. 16-12=4

4÷2 * 5*5
4÷2 * 25
2*25 = 50

Number 12 is correct.
