Grandpa is 56 years older than his grandson, and grandpa is exactly 8 times older than his grandson,

The grandson is doubled, the grandfather is 8 times, they are 7 times different, the difference is 56 years, so double is 8 years old, so the grandson is 8 years old, and the grandfather is 64 years old.

The grandfather is 7 times older than the grandson, so the grandson's age is 56 (8-1)=8, so the grandfather's age is 8 8=64

The age difference is 56, and the age difference is 7 times the age of the grandchildren, so the grandchildren are 8 years old. It would be more intuitive to draw a line segment diagram.

64 years old. Suppose: The grandchild is age x

8x-x=56 is obtained, then the grandchild is 8 years old, multiplied by multiples.

Grandpa is 65 years old this year, 2 years older than his grandson, how old is his grandson.

Xie Gaiji: Sun Hehui Jinzi is 9 years old this year. The grandson is x years old this year. The equation is 7 +2 = 65, 7 = 65-2, 7 = 63, =9, Answer: The grandson is 9 years old this year.

9 years old.

According to the rules of multiplication and division, it is known that the result of 55 6= is 9 years old.

年数 (years), a Chinese word, pinyin is suìshù, refers to the age of a person, and can also refer to the age of other things (i.e., the number of years).

This is and times the problem.

The age of the grandchild is: 72 (8+1)=8 (years).

Grandpa's age is: 72-8=64 (years).

8 years old. 8 8 = 64 years old.

A: Grandpa is 64 years old. The grandson is 8 years old.

This question can set the age of the grandson is x, the age of the grandfather is y, according to the question of the sum of the age of the grandson is 72, you can list the formula, x+y=72, and then according to the grandfather is 8 times the age of the grandson, you can list a formula, y=8x, so calculate x=8, y=64, so the grandfather's age is 64, and the grandson's age is 8.

Hello, this is a second-grade topic, grandpa is 64 years old, grandson is 8 years old, do the math.

Just use the words of x.

Suppose the grandson is x years old.

7x+3=x+57

7x-x=57-3

6x=54x=9Answer: The grandson is 9 years old.

The grandson is 7 times older than the 3-year-old grandfather.

Grandpa - grandson = 57 years old.

So 6 times the grandson is 3 years old = 57 years old, ask for grandson = (57-3) 6 = 9 years old grandfather = 9 + 57 = 66 years old.

Let an x be 7-1 if you subtract your grandson's x because the grandfather is 57 older than the grandson

This question is wrong, according to your answer, the grandfather is 66, the grandson is 9, but what he said is that the grandfather's age is 7 times the age of the grandson more than three years old, twice as much as him is 9 plus itself is 18, and pushing 7 times in turn is 9 * 7 + 9 is equal to 72, so the calculated answer 66 is not wrong.

Solution: If the grandson is x years old this year, then the grandfather is 57 x years old, then 57 x 4x

x 19 (years old).

57 x 76 (years).

Answer: Grandson, grandfather's age is 19 years old and 76 years old.

This is a difference problem, according to the title, grandpa is 4-1=3 times older than grandchild, so grandchild's age is: 57 (4-1)=19 years old, grandpa's age is 19 4=76 years old, I hope it will help you.

57 (4-1) 19 years old.

1 4 76 years old.

A: My grandson is 19 years old and my grandfather is 76 years old.

If the grandson is x years old, then the grandfather is 4x, so 4x-x=57, then x=19, and the grandfather is 76.

a-b=57，a=4b。Solve equations.

3b = 57, b = 19 years old grandchild. He is 76 years old.

Assuming the age of the grandson is x, then:

7x=x+60

7x-x=60

6x=60 then x=10, so the grandson is 10 years old.

10 + 60 = 70, so grandpa is 70 years old.

This question can be answered by an equation that assumes the grandson's age x, then the grandfather's age is 7x. In this way, according to the topic, we can get an equation x+60=7x, and this equation can be solved: x=10, that is, the age of the grandson is 10 years old, then the age of the grandfather is 7 10=70 years old.

Solution: Let the grandson be x years old and the grandfather be 7x years old.

7x -x =60

6x =60

x =107x =7×10=70

A: The grandson is 10 years old and the grandfather is 70 years old.
