Answer:
30
Step-by-step explanation:
f = 3(c)
f+20 = c+40
3c + 20 = c + 40
2c = 20
c = 10
f = 3*c = 3x10 = 30

ahh no this is the answer for another question, sorry lol
Answer:
45 Years
Step-by-step explanation:
Let the age of father be x years and sum of the ages of his children by y years.
After 5 years,
Father's age = (x + 5) years
Sum of ages of his children = (y + 10) years
From the given information, we have:
x = 3y ...(1)
and x + 5 = 2(y + 10)
x - 2y = 15 ...(2)
From (1) and (2), we have,
3y - 2y = 15 y = 15
x = 3y = 45
Father's age = 45 years
