Question

24 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:

1st Part = 13, 2nd Part = 11

Step-by-step explanation:

let first part be (x) and second(y)

x+y=24(y=24-x)

7x+5y=146

7x+5(24-x)=146

7x+120-5x=146

2x=146-120

2x=26

x=13

y=24-x

y=24-13

y=11

Therefore:x=13 and y=11
