The correct answer is 33.
Solution:
Consider the given equation.
22 + 3 = – 8
To determine the missing number, first, we need to find: 22 + 3.
Which gives:
22 + 3 = 25
Then,
22 + 3 = – 8
25 = – 8
Next, to find the missing number we find: 25 + 8.
Which gives:
25 + 8 = 33
So,
22 + 3 = 33 – 8
That is, number 33 makes the equation true.
