Mr. Cho received a container of fresh eggs. He sold 1/3 of the eggs in the morning and sold 320 eggs in the afternoon. At the end of the day, he found that 1/4 of the eggs were not sold. How many eggs did he receive in the beginning?

Step-by-step explanation:

So the algebraic expression here is:

let x-be the number of received eggs

1/3x + 320=(1-1/4)x

1/3x + 320 = 3/4x

Transposing 1/3x to the other side:

320=3/4x-1/3x

320=9/12x-4/12x

320=5/12x

Multiply both sides by 12:

3840=5x

Divided them both by 5:

x=768

So the answer is 768 eggs.

7 - 9 = -2

-2 + 9 = 7
