My sister and sister were born on the same day, why is there a difference of five years?

My sister's age five years ago is the same as my sister's age three years later, so how old is the difference between my sister and my sister?

The older sister and younger sister are at least 8 years apart.

My sister's age five years ago is the same as my sister's age three years later. , then the difference between sister and sister is 8 years.

Let's say my sister is X years old this year and my sister is y years old.

Then x-5=y+3

x=y+8

The elder sister was the same age as the younger sister three years ago, and the age of the younger sister five years ago was the same as the younger sister three years later. Then they are different, then they are 5+3 equals eight years old.

I come to this question, solve the problem that the age of 5 years ago is equal to the age of my sister three years later, and ask how old is the difference between my sister and my sister?

This doesn't have to be algebraic, and it's not xy.

The simplest algorithm is to say, 5+3=8

The older sister and younger sister are 8 years apart. That's the right answer.

This question can be asked like this:

According to the title, there are:

Sister's age -5 = sister's age +3

Sister's age - sister's age = 5 + 3 = 8 years old.

The age difference between the older sister and the younger sister is at least eight years.

A: The age difference between my sister and my sister is 8 years.

The older sister and younger sister are 9 years apart.

The result: my sister is 15 years old.

My sister is 10 years old.

Analysis: After 3 years, my sister and sister are growing up, so it has something to do with disturbing this 3 years of chaos.

15-5=10 (years).

Draw a line segment diagram:

Three years later, my sister was five years older than my sister.

My sister is 15 years old this year.

That sister was ten years old.

After all, three years later, your sister is stupid, and your sister is five years older.

In fact, my sister is five years older than my sister every year.

Therefore, Qin Nian is my sister who is fifteen years old today.

My sister is 10 years old.

According to the title, it can be seen that the same as 3 years later, this year's sister's age is 5 years older than her sister, and because the age of the two this year is 15, it can be seen that 2 times the age of the younger sister should be equal to 15-5=10 years old, so that the younger sister's age this year is 10 2 = 5 years old, and my sister's is 5 + 5 = 10 years old.

It should be that the two sisters should be five years apart, no matter how many years have passed, the difference is five years, so it should be said that the answer is that the sister is ten years old now, and the sister is five years old.

My sister was ten years old, my sister was five years old, and three years later, my sister was 13 and my sister was 8 years old.

This year, my sister is 22 years old and my sister is 13 years old.

The calculation is as follows: The age difference between the older sister and the younger sister is:

9 years old. So, now my sister's age is: 4 + 9 = 13 years old.

So, now my sister's age is: 13 + 9 = 22 years old.

The older sister is at least a year older than the younger sister.

There is no regularity in this one, and there are also 3-5 years older, and even 8-10 years older in the past years.

My sister's current age is 33, and my sister's age is 22!

Solution: 1) If the age of the sister is x, then the age of the sister is 55-x, that is, the age gap between the sisters is (55-x)-x=55-2x

2) A few years ago, the age of the sister was x, and the age of the macro sister was x 2, that is, the age difference between the sisters was x-x 2=x 2

Then: x 2=55-2x so x = 22

That is, the sister of the shelter town is 33 years old this year, and the sister is 22 years old this year.

Hope mine can help you.

If the age of the sister is 55 years old, then the age of the sister is the age of the year.

This year, my sister is 22 years old and my sister is 13 years old. Lameng.

The calculation is as follows: The age difference between the older sister and the younger sister is:

9 years old. Then, the age of the current wheel bridge in the younger sister is: 4 + 9 = 13 years old.

Therefore, my sister's age is now 13 + 9 = 22 years old.

5 years old. My sister is growing up, and my sister is growing up.

Then four years later, my sister is five years older than my sister, so I can calculate that this year's sister is (25-5) 2=10 years old, and my sister is 25-10=15 years old this year!
