I have to solve this problem do not understand

Chang picked 36 Apples and kept 8 of them. He split the remaining apples among his sister and brother most write an algebraic expression on how many his sister and brother got.

(36 - 8) / 2 = ?

To solve this problem, we need to account for the 8 apples that Chang kept for himself. Let's assume the number of apples that Chang's sister received is denoted by 'x' and the number of apples that Chang's brother received is denoted by 'y'.

We know that Chang picked a total of 36 apples and kept 8 for himself. Therefore, the number of apples he distributed to his sister and brother is (36 - 8), which simplifies to 28 apples.

Now, we can write the algebraic expression for the problem. The expression for the number of apples received by Chang's sister (x) and brother (y) is:

x + y = 28

This equation represents that the sum of the apples received by both the sister and brother is equal to 28.
