Let F = father's age
Let S = son's age
F = 3S
F - 5 = 4(S-5)
F - 5 = 4S -20
F = 4S - 15
F = 3S
3S = 4S-15
S = 15, age of son
son is 10, father is 33
The son is 24 and the father is 44 years
Age of the father is 20. Pretty young to be a father. Son is 8 years old. The equations are as folllows: x-2 = 3 (y-2) 2x = 5y Cheers
a father is 30 years older than his son.in 12 years,the men will be three times as old as his son.find their present ages.
"When you were 14 years old, your father was 42 years old". - that gives us the difference in age. The father is 42 - 14, or 28 years older than the child. "which was three times your age" - that's a decoy. It's true, 14 times three is equal to 42, but it doesn't tell us anything we don't already know. "now he is twice your age, how old are you?" - this is the other piece of information we need. Combining this with the first statement will let us find the answer: Let the father's age be "F", and the child's age be "C". We can then say that, given the first statement: F = C + 28 because that statement told us that the father is twenty-eight years older than the child. We can also say: F = 2C as that's what the last statement tells us. Now all we need to do is combine those two statements: F = C + 28 ∴ 2C = C + 28 ∴ C = 28 So the child is now 28 years old. You can also find the father's age by plugging it into one of the previous equations. We know that F = 2C, so the father's age is 2 * 28, which equals 56.

If x is the age of the son, then 5x would be the age of the father. In 6 years, the son would be x + 6 years old, where the father would be 3(x + 6) years old. Since the original age of the father is 5x, then in 6 years the father could also be said to be 5x + 6 years old. Setting these two expressions for the father's age as an equation, we then can solve for x, the son's age. 3(x + 6) = 5x +6 3x + 18 = 5x + 6 2x = 12 x = 6 The original age of the son is 6 and of the father (5x) is 30 years old. In 6 years, the son would be 12 and the father would be [3x + 18 or 5x + 6] 36 years old.

Penny is five years old. In 10 years she will be 15, which is three times her current age.
