Jackie has one sister. Jackie's sister is 4 years older than her. The girls' ages add up to 28. Write an equation to solve for Jackie's age. *

Jackie's age = 12 years and Her sister's age = 16 years

Step-by-step explanation:

Let the age of Jackie be x.

Her sister's age = (x+4)

The sum of ages = 28

ATQ,

x+x+4 = 28

2x+4 = 28

2x = 24

x = 12

Jackie's age = 12 years

Her sister's age = (12+4) = 16 years

Hence, this is the requiredsolution.
