I m a year old, my dad is 30 years older than my son, and in another 10 years, what is the sum of th

Son A years old and age after 10 years = A + 10 years old.

The father is 30 years older than the son, that is, the son's age A plus the father's 30 years older = (A age + 30 years) is equal to the father's current age, plus 10 years later = (a + 30) + 10

The formula is: A+10+

The guy above me came out of A+10+A+30, and it seems that he didn't count Dad's age to ten years later.

You look at the above tips, it is the age of the father and son ten years later, the son is 10 years older, the father can't still be A+30, right, and add 10 is the age of the father ten years later, that is, (A+30) +10

When doing the question, you must read the question clearly, otherwise the whole question will be wrong if there is one less condition.

If I miscalculated, please point it out to the landlord.

Let's say I'm a year old, and the sum of my father's age and my dad this year is a, and my father's eldest son is 30 years old, then my father's age is (a+30).

a=a+(a+30)=2a+30Ten years later, my father and I will have a total age of b ten years, and both father and son will be 10 years older, making a total of 20 years.

b=(2a+30)+20=2a+50

Answer: After 10 years, the sum of the ages of father and son is (2a+30) years.

I'm a year old this year, my dad is A+30, and in the next ten years, each plus ten years old, isn't it equal to A+10+A+30, and simplifying it is equal to 2A+40

Son this year: A year old Father this year: A+30 years old Ten years later Son: A+10 Ten years later Father: A+30+10 Ten years later, father and son age only: A+10+A+30+10=2A+50

30 years old.

The father is 30 years older than the son, whether it is 5 years later, or 10 years later, the father's age is always 30 years older than the son's age, because the son's age is growing, and the father's age is also increasing, so the father is 30 years older than the son.

Age is also known as "age" and refers to the length of time a person has lived from birth to the time of calculation, and is usually expressed in years. Age is a natural sign with a biological basis, and it is an irresistible natural law that a person is disturbed after birth, and as the days and months pass, the age also increases.

A: 30+A years old.

Because the father is older than the son, addition is used.

Because, three years ago, the father's age = the son's age + 30 years old;

Father's age = 3 Son's age 2 years old;

So, three years ago, the son's age + 30 years = 3 the son's age 2 years old;

The age of the son = 32 years old 2 = 16 years old, so, now, the age of the son = 16 years old + 3 years old = 19 years old Kai Hu Wei.

Solution: Let the age of Jeno's father be y, and the age of his son be x

Because the father is 30 years older than the son (it doesn't matter when the god shouts, it doesn't change), so y=x+30

Three years ago: father Y-3 years old, blind son X-3 years old.

y-3=3×(x-3)-2

So y=3x-8

Substitute y=x-30.

Get x=19

So now my son is 19 years old.

Three years ago, my father was 28 years older than my son. As we all know, my father's age this year is my son's three rents and is two years younger than me. How old is my father, please.

If the son is x years old this year, the father is, x=15, so x+28=15+28=43, so my father is 43 years old.

If the son is x years old this year, then the father is x + 30 years old this year, so:

x+30+1=3（x+1）

The solution is x=14

So the son is 14 years old.

The process of solving the equation:

x+30+1=3（x+1）

x+31=3x+3

x-3x=3-31

2x=-28

x=14

At the age of 14, you can solve binary equations! Suppose the father is x years old and the son is y years old x-y = 30

x+1）/(y+1)=3

Solution: y = 14 years old.

My father was 44 years old.

The son is 14 years old and the father is 44 years old.

Let's take my son's age this year.

a, then the paternal age is.

30＋a30＋a＋1＝3×(a＋1)

Solve the equation and get.

a＝14

Son: 30 divided by 2 equals 15 years old Father: 15 times 3 equals 45 years old.

I'm a year old, my father's eldest son is thirty years old, my father: a+30, total: 2a+30

Ten years later, I am ten years older, and my father is ten years older, a total of 20 years old. Sum of ages: 2a+50

It depends on whether you are a father or a son. If it is a son, and is 50+2a; If it's a daddy, and it's 2a-10. Right?

Dad's age a + 30) + (son a year) = the sum of father and son ages.
