The ratio of the ages of two sisters are 4:3. The older sister is three years older than the younger sister. How old is the younger sister?​

Respuesta :

Answer:

The Younger sister is 9

Step-by-step explanation:

x = age of older sister

x - 3 = age of younger sister

4/3 = x/(x - 3)

Solve for x.

4(x - 3) = 3x

4x - 12 = 3x

x = 12

The older is 12, the younger is 12 - 3 = 9
