Answer:
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.
