This year, father and son are 44 years old. Ten years later, father is three times as old as son. How old is father this year

This year, father and son are 44 years old. Ten years later, father is three times as old as son. How old is father this year

Suppose Laozi is x years old and his son is y years old
x+y=44
x+10=3(y+10)
x=38 y=6

Father and son are 40 years old this year. Six years later, father's age is three times that of son's. how old are father and son this year?

Son: 7; father: 33
Formula: 40 + 6 × 2 = 52 (years old) {the sum of father and son's age after six years}
52 (3 + 1) = 13 (years old) {father three times, son one time, a total of four times, ask the son's age in six years}
13-6 = 7 (years old) {the age of my son this year}
40-7 = 33 (years old) {father's age this year}

Now the age of the son is eight, and the age of the father is four times that of the son. X years later, the age of the father is three times that of the son, so x is ()
A. 3B. 4C. 5D. 6

Suppose that the age of the father is three times that of the son after X years
