Answer:
n is 6
Step-by-step explanation:
because sum means addition and if you subtract 9 by 3, you get 6, so we now know that the missing number is 6 because when you add 6 and 3, you get 9. :)
Given,
A number = n
Number added to it = 3
The two numbers sum is = 9
Therefore, by the problem,
=> n + 3 = 9
=> n = 9 - 3
=> n = 6
Hence, required value of n is 6 (Ans)
