Question 151287: I could really use help with these problems. This is homework out of a college math book called Thinking Mathematically, Chapter 9 problems 6,18,26,46,56. The problem reads:

Question 151380: Six years ago bob was four times as old as Mary. In four years he will be twice as old as Mary. How old are they?
Six years ago
Bob = 4Mary - 6
In four years
Bob = 2Mary + 4
4M - 6 = 2M + 4
2M = 10
Mary = 5 years old
Substitute both equations with 5, and Bob is 14
I just want to know if that is right or wrong?
