A pile of apples sells for 200 kilograms, and there are 350 kilograms left, how many kilograms are t

Let this pile of apples be the original x kilograms.

x-200=350

x=350+200

x = 550 kg.

Let's say the pile weighs x kilograms.

x-200=350

x=350+200

x = 550 This pile of apples has 550 kilograms.

Column equation solving problems.

Solution: Let's say this pile of apples has x kilograms.

x-200=350

x-200+200=350+200

x=550A: There are 550 apples in this pile.

Extended Materials. General steps for solving problem solving column equations:

1.Understand the topic. Read the question carefully, understand the meaning of the question, and understand the known conditions and the questions you are asking for.

2.Analyze the problem. If it is a fraction problem, you can draw a line diagram to help you understand.

3.Find equiquantitative relationships. This is the key step in solving this kind of problem, finding the equivalence relationship in the problem, this is the most important step...

4.Column equations, solving equations. Set the unknown to a letter, usually x, according to the equation of the equivalence off series, and solve the equation.

5.Test and write the answer When testing, one is to substitute the value of the unknown obtained for the Taiyuan equation to test whether the solution of the equation is correct; The second is to check whether the value of the unknown obtained is in line with the topic, and if it does not meet the topic, it should be discarded and the solution that conforms to the topic should be retained

A pile of apples sold 25% is 60 kilograms more than it was sold, and how many kilograms of apples were there in this pile.

Hello, the answer is 120 kg. The remaining 60 kg is 1-25%-25% = 50%, so there is 60 50% = 60 kg. Hope mine can help you <>

Summary. A certain apple in the supermarket is 15kg per box, 65kg is sold, and there are 25kg left, how many boxes of apples are there? Solve with column equations.

It's too slow.

The solution process is:

If a basket of apples has x thousand difference celery grams, then sell 30%x kilograms, and the remaining (x-30%x) kilograms, according to the title, you can get:

x-30%x)-30%x=24

Solution x = 60 kg.

So, 30% x = 18 kg.

So, sell 18 kg of apples.

Hello: The equation is solved as follows: x 3=25

x=25×3

x=75, so the total weight of the last basket of apples is 75 thousand grams!

A box of apples 30 kilograms sold for 240 yuan, so.

240 30 8 yuan per kilogram.

Let X yuan per kilogram of apples, then.

30x =240

x = 8 A: 8 yuan per kilogram of apples.

570-200+30)*2=800 (kg).

The original 800 kilograms of calendar core, half of the pants were sold and 30 kilograms, that is, 400 + 30 = 430 kilograms, the remaining 370 thousand grams of rotten remaining, plus 200 kilograms of re-entering, the existing 570 kilograms.
