Answer 2

Answer:

Step-by-step explanation:

Let Sydney's number be y

and Robin's number be x

given, y = 8 + x

also, given that

x + y = 72

substitute for the value of y

x + 8 + x = 72

2x = 72 - 8

2x = 64

x = 32

x + y = 72

32 + y = 72

y = 40

therefore Robin's number is 32

Sydney's number is 40
