C

D

The correct answer is 58.
Solution:
Consider the given equation.
48 + 4 = – 6
To determine the missing number, first, we need to find: 48 + 4.
Which gives:
48 + 4 = 52
Then,
48 + 4 = – 6
52 = – 6
Next, to find the missing number we find: 52 + 6.
Which gives:
52 + 6 = 58
So,
48 + 4 = 58 – 6
That is, number 58 makes the equation true.
