Question

twenty four is divided into two parts such that 7 times the first part added to 5 times the second part makes 146. find each part.

Answer 1

Answer:

The two parts are 13 and 11

Step-by-step explanation:

Let the 2 parts be x and y such that,

x + y = 24 ------- equation 1

At the problem,

7x + 5y = 146 ------- equation 2

now multiplying 5 to equation 1 gives,

5x + 5y = 120

now subtract equation 2 from 1,

7x + 5y = 146

5x + 5y = 120

we get, 2x = 26

thus, x = 13.

y = 11 (24-13)

thus the 2 parts are 13 & 11....
