Answer:

Dog is 2 years old

Step-by-step explanation:

Let dog's age = d

Let friend's age = f

Your dog is 8 years younger than your friend:

d +8 = f

In 2 years, your friend will be three times as old as your dog:

3(d+2) = (f+2)

3d+6 = f+2

3d = f - 4

(sub in f=d+8 from above)

3d = f - 4

3d = d+8 - 4

2d = 4

d = 2
