Question

seventy-two is divided into two parts such that twelve times of first when added to the five times of second parts makes 472. Find each part.​

Answer 1

let the two parts be x and 72-x.

according to the statement given above:

12x + 5(72-x) = 472

12x - 5x + 360 = 472

7x + 360 = 472

7x = 112

x = 16.

first part = x = 16

second part = 72-x = 56
