Your friend has owned a dog for 11 years. This is one year less than 2 as long as he has owned a cat. How long has your friend owned a cat?

He pet the cat at least 13 years

Step-by-step explanation:

11 + 2 = 13

But less than 2 mean the dog's years is less cat's years 2 years, but less than can be more on cat, so if the number above 2 or equal 2, then it was right.

x >= 2
