Answer:
-18
Step-by-step explanation:
x=???
First, we know that the number we are looking for is divisible by 3. So lets list so numbers that are divisible by 3:
all (+,-) 6,9,12,15,18,........
Second, since we know the answer has to be in the double digits from the list we can have only 3 possibles answers.
12÷3=4
4-4=0
-12÷3=-4
-4-4=-8
So 12 nor -12 cant be the answer
18÷3=6
6-4=2
-18÷3=-6
-6-4=-10
So, the answer to the problem is -18÷3-4=-10
