Answer:
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
