Directions: What approximate value will come in place of the question mark (?) in the following question? 24 - 2 [18 ÷ (? + 1)] = 43 - (5²)

Evaluate the right side of the equation by calculating 5 squared as 25, then subtracting it from 43 to get 18. The equation becomes 24 minus 2 times the quantity 18 divided by the quantity of the missing value plus 1, equals 18. Subtracting 18 from both sides gives 6, equals 2 times the quantity of 18 divided by the missing value plus 1. Dividing by 2 leaves 3 equals 18 divided by the missing value plus 1. Multiplying by the missing value plus 1 gives 3 times the missing value, plus 3, equals 18. Subtracting 3 and dividing by 3 results in the missing value being 5.
