Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The sum of Andrew's age and Chris' age is 67. Let b represent Beatrice's age.
Write an equation that would help determine Beatrice's age.

Beatrice's age is 34

Step-by-step explanation:

Beatruce = B

Andrew = B+2

Chris= B-3

B+(B+2) +(B-3 )= 67-B

3B-1 = 67-B

2B -1 = 67

2B= 68

B = 34

Beatrice is 34

Andrew is 36   (34+2)

Chris is 31 (34-3)

36+31 = 67
