The correct answer is 35.
Solution:
Consider the given equation.
+ 5 = 47 – 7
To determine the missing number, first, we need to find: 47 – 7.
Which gives:
47 - 7 = 40
Then,
+ 5 = 47 – 7
+ 5 = 40
Next, to find the missing number we find: 40 – 5.
Which gives:
40 – 5 = 35
So,
35 + 5 = 47 – 7
That is, number 35 makes the equation true.
