The johnson twins were born two years after their older sister. this year, the product of the three siblings ages is exactly 4558 more than the sum of their ages. how old are the twins?

Let T = the twins' ages Then, the older sister is of age 2 + T.

the product of the three siblings ages is T*T*(T+2)

the sum of their ages. (T + T + (T + 2))

Using those equations and your calculator, you can now calculate the age of the siblings. 

I hope that helps you.
