The school buys 10 sets of desks for 500 yuan, and the unit price of the table is known to be 4 time

If the unit price of the chair is x, and the unit price of the table is four times that of the stool, then the unit price of the table is 4x. According to the question, ten sets of tables cost 500 yuan. Get the following equation.

Solution: Let the unit price of the chair be x to get the following equation:

x+4x)*10=500

5x=50x=10

Therefore, the unit price of the table is 4*10=40

1. The relationship between equations and equations: Equations must be equations, but equations are not necessarily equations. In the definition, the equation must be an equation, but the equation can have others, such as 1+1=2, 100 100=10000 as mentioned above, all of which are equations, and obviously the range of equations is a little larger.

2. Solve equations.

Basis: Shifting terms: Moving certain terms in the equation from one side of the equation to the other with the previous symbols, and adding and subtracting, subtracting, multiplying and dividing, and dividing by multiplication.

Basic properties of the equation:

3. Property: Add (or subtract) the same number or the same algebraic formula on both sides of the equation at the same time.

The result is still the equation. It is expressed in letters as: if a=b, c is a number or an algebraic formula.

4. If both sides of the property 2 equation are multiplied or divided by the same non-0 number at the same time, the result is still the equation. It is expressed in letters as: if a=b, c is a number or an algebraic formula (not 0).

5. Property 3 If a=b, then b=a (symmetry of the equation).

6. Property 4: If a=b, b=c, then a=c (transitivity of the equation).

7. Method 1 of the steps of solving the equation: 1What can be calculated is calculated first; 2.Conversion - Calculation - Result Method 2: Calculate from the front to the back, and you can calculate directly when there is only one number left.

Set the stool ** for x yuan, then the table ** is 4x yuan x + 4x for a set of desks**, that is, 5x yuan to buy a total of 10 sets, that is, 5x times 10, spend money 500, that is, 50x = 500x = 10 yuan Answer: The unit price of the stool is 10 yuan, and the unit price of the table is 40 yuan.

$40. Ten sets of 500, one set is 50

Let x be a stool.

x+4x=50

x=10 so the stool is $10 and the table is $40.

Or: 500 10 = 50 (yuan).

$40.

Ten sets of 500, one set is 50, let x be the stool, x+4x=50, x=10 so the stool is 10 yuan, and the table is 40

Let the table be x, then the table is x, so the table is forty yuan.

The school buys a set of desks for 480 yuan, of which the table is 40% more than the chair, the chair is 480 with (1 + 1 + 40%) = 200 yuan, and the desk is 480-200 = 280 yuan.

Summary. Hello, this question can set the ** of the stool to be X yuan, then the ** of the table is 4X yuan.

x+4x=1150 yuan.

5x=1150

x = 1150 5 = 230 yuan, so the ** of the stool is 230 yuan, and the ** of the table is 4x = 230 4 = 920 yuan, so the unit price of the table is 920 yuan.

The school bought ten sets of desks, a table with a stool, and used it for 1,150 yuan, and the unit price of the known table was 4 times that of the stool, per +

6360 53 = 120 (dust Hu Yuan).

120 (2+1)=40 (RMB).

120-40=80 (yuan).

Therefore, the unit price of the table is 80 yuan, and the unit price of the Yuanxiao stool is 40 yuan. Hail brother contains.

The class is 100 yuan for the desk or resistance, and the chair is 25 yuan.

Solution: Set the chair x yuan.

4x-x=75

3x = 753x divided by 3 = 75 divided by 3

x=2575+25=100 yuan.

Answer: The table brother group model is 100 yuan, and the chair is 25 yuan.

Because the table is 4 times that of the stool, the line is definitely 3 times more than the stool, and the table is known to be 75 yuan more than the stool. So the stool is 75 3 = 25 yuan. The table is 4 25 = 100 yuan.

Set $x per stool. The table is 4x.

10*（x+4x）=500

5x=50x=10

So 4x=40, the table is $40.

Set the stool ** for x yuan.

Then the table ** is 4x yuan.

x+4x is the ** of a set of desks.

That's 5x yuan.

I bought a total of 10 sets, that is.

5x multiplied by 10 costs 500 money

i.e. 50x=500

x=10 yuan.

A: The unit price of the stool is 10 yuan, and the unit price of the table is 40 yuan.

Think of the unit price of a stool as unit 1 and the unit price of a table as 4.

Stool: 500 divided by (4+1) = 100

Table: 100x4=400
