a father is 43 years old and his 2 children is 8 and 6 years old. how many years will the sum of the ages of the two children be until they're twice the father's age?

Step-by-step explanation:

29 years they are combined ages the same and if this goes up 2:1 ratio every year thereafter from age 43 then to change 29:43 to make double it is x 8 43 x 8 = 344 and 29 x16=464. The ages never become double.
