Answer 1

Step-by-step explanation:

let x be his younger brother weight and his weight be 2x

Now, x+2x=78

implies 3x=78

implies x=78/3 =26

therefore Joseph's weight is 2×26=52 as his weight is two times greater than his younger brother

Answer 2

Answer:

52

Step-by-step explanation:

Let weight of younger brother be X

weight of Joseph =2X

sum of their weight =78

2x+x= 78

3x =78

x=26

so weight of Joseph = 2x=52
