Question

find two numbers such that one of them exceeds the other by 9 and their sum is 21

Answer 1

let one number = x

other number exceeds the other by 9 = x+9

their sum = 21

according to the sum,

x+x+9= 21

2x = 21-9

2x = 12

x = 12/2 = 6

one number = x = 6

second number = x+9 = 6+9 = 15
