Solve and express the following in the terms of b and or c.
1. Barry's age in 4 years
2. Clair's age 2 years ago
3. The sum of their ages 4 years ago
4. The sum of their ages 4 years hence
5. Barry is half as old as Clair
6. Clair is thrice as old as Barry
7. Four years ago, Barry was one-third as old as Clair was
8. Next year, the sum of Barry's age and Clair's age will be 26

Answer 1

1. 4
2. c-2
3. b-4+c-4
4. b+4+c+4=b+c+8
5. b=(c/2)
6. 3b=c
7. 3(b-4)=c-4 OR 3b - 12 = c -4 OR 3b - c - 8 = 0
8. b+1 + c + 1 = 26 OR b + c = 24
