Paco signed up for a gym membership 17 weeks after Marlon

Let 'a' represent the number of weeks Paco has been a member and 'b' the number of weeks Marlon has been a member

Find the value of 'b' when 'a' = 3

Here b = - 14

Step-by-step explanation:

The number of weeks Paco has been a member : a

The number of weeks Marlon has been a member : b

Now, according to the question

b + 17 = a

Now, here given a = 3

So, b + 17 = 3 or, b = 3 - 17 = - 14

⇒ b = - 14
