Find the ages of A and B from this information: 6 times A's age is 100 more than 5 times B's age, and 9 times A's age is 170 more than 7 time's B's age.
**
let A=A's age
let B=B's age
..
6A=100+5B
9A=170+7B
..
42A=700+35B
45A=850+35B
subtract:
3A=150
A=50
..
5B=6A-100
5B=300-100
5B=200
B=40
..
A's age=50
B's age=40
