Answer: Hence, Option (6) and (8) are correct as their value is also "-8".
Step-by-step explanation:
Since we have given that

First we need to solve to get the value of 'x' :

Therefore, x=-8
Now, we will check all the options :
1) 4x+8=24

2) 9x+18=-24

3) 4x+12=-24

4) 18x+36/2=-24

5) 4x=-36

6) 4x=-32

7) x=-9
8) x=-8
Hence, Option (6) and (8) are correct as their value is also "-8".
