Can anyone help me solve this equation 20 for the fifth grade of elementary school

The grain store brought in a batch of rice and flour, the weight of rice is twice that of flour, after selling 350 kilograms of rice, the rice weighs the same as flour, how many kilograms of rice and flour are transported by the grain store?

Solution: If the flour brought in by the grain store is x kilograms, then the rice is, and the question is obtained

x A: The grain store brought in 1,225 kilograms of rice and 875 kilograms of flour.

After selling 350 grams of rice, the rice weighs as much as the flour, and how many kilograms of rice and flour are transported by the grain store?

Solution: Let flour be x and rice be x.

x 875 A: 1,225 kg of rice and 875 kg of flour were brought in from the grain store.

Set up to transport x kg of flour.

x = 875 A: 875 kg of flour and 1225 kg of rice were brought in.

Let the flour be: x

Rice is x = 875 and flour is 875 grams.

Rice is 875* grams.

1)24-6x=15

Solution: 24-15=6x (shift).

6x=9 (merge similar items).

x = coefficient of 1).

So, x= is the solution of the original equation.

2) Is this inscription correct? )

Solution: 45-5x=

5x = move items, merge items of the same kind).

x = coefficient of 1).

So, x= is the solution of the original equation.

3)25x-16x=

Solution: 9x = merge similar terms).

x = coefficient of 1).

So, x= is the solution of the original equation.

4) Solution: remove parentheses).

Move items, merge items of the same kind).

x = 18 (coefficient of 1).

So, x=18 is the solution of the original equation.

5) Solution: x=21 (move terms, merge similar terms).

So, x=21 is the solution of the original equation.

6) Solution: 700x=98 (multiplication of both sides of the equation by 1000) x=the coefficient of transformation is 1).

So, x= is the solution of the original equation.

7) Solution: Move items, merge similar items).

x = coefficient of 1).

So, x= is the solution of the original equation.

Solution: 4x = move terms, merge similar terms).

x = coefficient of 1).

So, x= is the solution of the original equation.

In fact, it is enough to do so much, and the equation only seeks to master the method, not to do all the problems in the world.

Let the first barrel have x kilograms and the second barrel have kilograms.

x = kilograms of oil in the first barrel.

Solution: The first barrel has x kilograms of oil.

Got: x=

It's simple, just like arithmetic.

Unknowns in equations are generally denoted by x, or y.

Addition] For example: 2+x=5 Analysis: x is the addition, addition = and - another addition. Solution: x=5-2

Subtraction] For example: 5-x=2 Analysis: x is the subtraction, subtraction = subtraction-difference. Solution: x=5-2

Multiplication] For example: 2*x=10 Analysis: x is a multiplier, multiplier = product another multiplier. Solution: x=10 2

Division] Example: 10 x = 2 Analysis: x is the divisor, divisor = quotient dividend. Solution: x=10 2

If you don't understand, you can ask. Satisfied.

Number + x = number.

Number + x = number.

Number + x = number.

Number + x = number.

Generally speaking, there is only addition, subtraction, multiplication and division.

Equal to the left of the sign, next to the number is the + sign, then x is -, yes-, yes is added, yes is (generally that's all.。。 ）

Analysis: Set the first group of x people, transfer 10 people from the first group to the second group It can be seen that the first group -10 is x-10, then the second group +10 is x+10, x is a small group to the second group of people, from the number of people in the second group is exactly 2 times that of the first group, it can be seen that the current first group is twice = the current second group of people, so the equation (x10)) 2=x+10 Understand.

Hello: Solution: Let's say there are x people in each group.

x-10）×2=x+10

2x-20-x+10

x=20+10

x=30A: Originally, there were 30 people in each group.

Solution: Let the first group have x people, then the equation is.

2(x-10)=x+10

Solution x=30

Solution: Set the width to x

x+2x）*2=

6x=x=2x=square meters.

A: The length of the painting, the width of the meter, the area of square meters.

Solution: If the width is x, the length is 2x

x+2x)*2=

6x=x=so the length is 2*the area is.

The length is, the width is, and the area is square meters.

Solution: Let the width be x, then the length is 2x. x+2x= 3x= x= x= 2x=length area:

A: ...

Hello! We'll be happy to answer for you.

Solution: x=6 divided by.

It's an equation solving problem, and it's very simple. How many times do you want to multiply? 30, of course.

Solution: If amateur athletes run x meters per minute, half an hour is equal to 30 minutes.

295-x)x30=600

295-x=20

x=275A: An amateur athlete runs 275m per minute

Amateur athletes run an average of XM per minute

30x=30×295-600

30x=8250

x = 275 amateur athletes run an average of 275m per minute

Athletes run an average of x meters per minute. The column equation is: 30x+600=295 30. The solution is x=275
