Answer:
5 years
Step-by-step explanation:
43 + x = 2(8 + x + 6 + x)
43 + x = 2(14 + 2x)
43 + x = 28 + 4x
3x = 15
x = 5
Note: your English is not correct, therefore the question is invalid.
I believe the question should be something like this:
A father is 43 years old and his 2 children are 8 and 6 years old. How many years will pass until the sum of the ages of the two children will be exactly a half of their father's age?
Answer: In 5 years, since 13 + 11 = 24 ----> half of 48
