Kailyn Rasmussen · Answer 1

Let n be Martin's sister's age. Then Martin is n-6. So:

n+n-6≤22

2n≤28

n≤14

n-6≤8

The oldest Martin's sister can be is 14.

Layton Knight · Answer 2

sisters age = x

martins age = x-6

equation: x + (x-6) <=22

2x - 6 <=22

2x<=28

x< = 28/2

x< = 14 (Sisters age is no more than 14)
