Question

write an equation to show how many groups of the sum of 4 + b equal 24.
4 + b
4 + b
24
24 = (4 + b) + (4 + b)
□ = □ (□)
4 + b
24
3
2 + b
2
3 + b

Explanation:

Step1: Identify repeated terms

The sum $4+b$ appears 2 times, and their total is 24.

Step2: Rewrite as multiplication

Repeated addition of a term is equivalent to multiplying the term by the number of times it is added.
$$24 = 2(4+b)$$

Answer:

$24 = 2(4+b)$
