Question

Suzanne is 4 years elder to her brother Robert. If the sum of their ages is 22 years, find the age of Robert. *​

Answer 1

Step-by-step explanation:

let 'x' be the age of Robert.

(x+4) + x = 22

2x + 4 = 22

2x = 22 - 4 = 18

x = 18/2 = 9

Age of Robert is 9 years.

Answer 2

Let Age of

Robert be y

Suzanne be y+4

so , According to Question

y + y + 4 = 22

2y = 22-4 = 18

y = 9 , y+4 = 13

so ,

Age of Robert is 9 years

Age of Suzanne is 13 years
