John is twice as old as bill. greg is 7 years older than bill. four years ago, the sum of their ages was 55. how old is greg?

Greg is 67 years old.

Step-by-step explanation:

John = 2 * B

G = 7 + B

J - 4 + B - 4 + G - 4 = 55

J + B + G = 67

2B + B + 7 + B = 67

4B = 60

B = 15

J = 30

G = 22

30 + 15 + 22 = 67

67 = 67
