    Set: Warehouse B originally had x tons of grain, and warehouse A originally had 2x tons of grain.

    2x-900)/350=x/250

    10x-4500=7x

    3x=4500

    x=1500

    2x=3000

    Answer: Warehouse B originally had 1,500 tons of grain, and warehouse A originally had 3,000 tons of grain.

    Solution: After X days of transportation, warehouse A originally had 350x+900 tons.

    Warehouse B originally had 250x tons.

    350x+900=2×(250x)

    350x+900=500x

    500x-350x=900

    150x=900

    x = 6 A warehouse originally had 350x + 900 = 350 6 + 900 = 3000 tons.

    Warehouse B originally had 250x=250 6=1500 tons, and I had to use my brain.

    Let's say warehouse B originally had x tons of grain.

    2x-900)÷350=x÷250

    x=1500

    Warehouse A originally had 1,500 * 2 = 3,000 tons of grain.

    If A is 2x B is x, then x 250 is the number of days to be shipped.

    2x-350*x/250=900

    x = 1500 tons.

    A is 3000 and B is 1500

    The grain in warehouse A is five times that in warehouse A, and the grain in warehouse A is transported to warehouse B by 180kg after the grain in warehouse B is equal in quantity. May I ask if the two warehouses talk about how much grain in the warehouse is more than a kilogram of food.

    You are noisy, very happy with your question, the grain in warehouse B is 90 kilograms, the grain in warehouse A is 450 kilograms, we can set the grain in warehouse B as x kilograms, so the grain in warehouse A is 5x, and then the grain in warehouse A is sent to warehouse B for 180 kilograms, and the amount of grain in the two warehouses is equal, so we can get 5x- 180 x+180, so the solution is equal to 90, and 5x is equal to 450

    Exercise: If 90 tons of grain are shipped out of warehouse A and 10 tons are transported out of warehouse B, then the grain stored in the two warehouses is equal, how many tons of grain were stored in each of the two warehouses?

    Solution: If warehouse B originally stored x tons of grain, then warehouse A originally stored 3x tons of grain, and the equation is listed according to the question.

    3x-90=x-10

    3x-90-x+10=0

    2x-80=0

    2x=80x=40

    A warehouse: 40 3 = 120 (tons).

    Answer: Warehouse B originally stored 40 tons of grain, and warehouse A originally stored 120 tons of grain As we all know, mathematics is different from Chinese and English, and mathematics has always been logical thinking.

    A relatively strict subject, the steps of answering the questions, and the final answer are all relatively standardized, what is right is right, and what is wrong is wrong. So, in general, mathematics is a polarized subject, with good grades getting better and better, and poor grades getting worse and worse.

    Of course, in terms of mathematics learning in primary school, it is relatively simple, and students want to get a high score, the premise is to grasp the basic knowledge well, and then understand the application problems that pull the most points, so it can be said that the mathematics results in primary school do not have to worry. The most important thing is to practice more on the basis of understanding and improve thinking skills.

    In the process of learning mathematics, students occupy an important position in thinking, and thinking is formed on the basis of mathematical knowledge and mastery methods. In order for students to acquire mathematical thinking ability, it is necessary to use students' existing mathematical concepts as the basis, use students' existing mathematical knowledge, flexibly deal with new problems, and understand mathematical objects and master new knowledge through mathematical judgment and reasoning.

    As far as primary school mathematics textbooks are concerned, the content is also relatively diverse, including Olympiad mathematics.

    There is also more knowledge of thinking, and parents do not have to deliberately send their children to Olympiad cram schools.

    Children can practice some simple math problems at home.

    Olympiad thinking is to learn how to think and solve problems, children can be exposed to relatively complex Olympiad problems after the third grade, stimulate students' learning motivation and interest in Olympiad training.

    If A granary has x tons, B has x 4 tons, according to the title.

    x-60=x/4+60

    Solution x=160

    Therefore, the first warehouse originally stored 160 tons of grain each.

    The second warehouse originally stored 40 tons of grain each.
