Question

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

Answer 1

Answer:

let the 2 parts be x and y

since, 24 is divided into two parts

therefore,

x+y=24 ..........(i)

also 7 times the first part added to 5 times the second part equals to 146

therefore,

7x+5y=146 ..........(ii)

multiplying equation (i) by 5 and subtracting (i) from (ii)

therefore,

7x+5y=146

-(5x+5y=120)

=>2x=26

=>x=13

so,y=24-13=11

hope you got it
