Please answer today, I will give crown when I can :) What's part B? Please make sure your answer is correct!

A) k = s - 4

B) s = 17

Step-by-step explanation:

Part A:

Let k be Katie's age and s be Sylvia's age.

Since Katie is 4 years younger than Sylvia, we need to subtract 4 from Sylvia's age.

So, the equation is:

k = s - 4

Part B:

Given that k = 13

Put in the above equation

13 = s - 4

Add 4 to both sides

13 + 4 = s

17 = s

OR

s = 17

Hope this helped!
