Give me 50 ways of a one dimensional equation write the whole process .

2x 10 1=7 2x=7-1 2x=6 x=6 2 x=3 You just give me the title and I'll write it all for you?

50 questions and 50 points, check it slowly, you are idle when everyone else is fine, others will give more than 20 questions, and you are only 50 if you have 50 questions

Set up a missing celery t minutes.

The two of them spent the same amount of time, and the second time they met, Liu Hai ran two more laps than Zhang, and Liu Hai ran 40 meters more per minute.

40t = 800, t = 20 minutes.

Liu Hai and Zhang Cheng ran on the 400-meter track, and the two stared at the same place at the same time, and it is known that Liu Kai's speed with the sea is 40 meters faster than Zhang Cheng's speed per minute, and it took him how much time it took for the two to meet for the second time.

If the question is okay, then there must be two pre-seepage answers (in fact, this question is simple to death, you can definitely figure it out with your brain).

1，4x=24

2，1700+150x=2450

3，4，5x-4x=-25-20

5，（3x+1）/2-2=（3x-2）/10-（2x+3）/56，5(3x+1)-10×2=(3x-2)-2(2x+3)7，7 + 9 x= 2

11 + 20 x= 2

18 - 14 x= 9

13 + 15 x= 10

4 - 2 x= 11

12 + 16 x= 2

8 - 3 x= 1

16 - 9 x= 4

19 - 18 x= 4

6 + 16 x= 4

13 - 5 x= 9

14 - 2 x= 5

3 + 13 x= 2

13 + 19 x= 8

6 + 8 x= 1

17 + 18 x= 1

14 + 15 x= 7

12 + 13 x= 6

16 - 5 x= 5

11 - 10 x= 11

4 + 10 x= 9

18 - 7 x= 3

15 - 7 x= 9

6 + 6 x= 11

15 + 16 x= 7

Think about it for yourself, it's simple.

In a univariate equation, the denominator step is usually multiplied by the least common multiple of each denominator, and if the denominator is a fraction, it can be multiplied by the reciprocal of the fraction on the denominator for the other parts of the term. [2]

Take the equation. For example:

Eliminate the fraction on the denominator and reduce it to :

The solution of the equation is derived.

If there is an irrational number on the denominator, you need to rationalize the denominator first.

Finding the Root Formula Method.

Basic formula. For about.

A one-dimensional equation.

The formula for finding the root is:

Derivation process. Solution: Shift, get: filial piety.

The coefficient is reduced to 1, and the :

Image method. For about.

A one-dimensional equation.

You can do this by making a function once.

to solve. A one-time equation for the bridge element.

The root of the is the primary function to which it corresponds.

When the function value is 0, the argument.

value. That is, the abscissa of the intersection point of the primary function image and the x-axis. [3] Primary function. Take the equation.

Image. The image is known from the image to the intersection of the x-axis at the point.

The root of the available original equation is.

Research applications. Basic application.

Unary equations can often be used for mathematical problems,[1] and can also be applied to calculations in physics and chemistry.

For example, in production and life, through the known certain density and pressure of the liquid, through.

The equation is substituted to solve the equation to calculate the depth of the liquid. For example, if we calculate the pressure generated by the water column at which the atmospheric pressure is about equal to how high, we know that the atmospheric pressure is about 100,000 pascals, the density of water is about 1,000 kilograms per cubic meter, and g is about 10 meters per square second (10 N per kilogram), then the height of the water column can be set to be h meters, and the equation is 1000*10h=100000, and the solution is h=10, and the atmospheric pressure is about equal to the pressure generated by the water column of 10 meters.

Solution: 10 3*(200 x) 5(300 x) 300 25 9 Both sides of the equation are multiplied by 3

Get 10*(200 x) 15(300 x) 100 25, that is, 2000+10x-4500+15x=250025x=5000

x=200

That is, 10 3 (200 + x) - 5 (300-x) = 300 * 25 92000 3 + 10x 3-1500 + 5x = 300 * 25 925x 3 = 2500 3 + 2500 3

25x/3=5000/3

So 25x=5000 so x=200 use mine.

3/3000 Ex minus 1500 Ex divided by 5 equals 2500 3/3

There are x boys and 54-x girls.

According to the title. 3x+2(54-x)=137

3x+108-2x=137

x=2954-x=54-29=25

There are 29 boys and 25 girls.

Solution: There are x boys in this class, according to the topic.

3x+2(54-x)=137

3x+108-2x=137

3x-2x=137-108

x=29A: There are 29 boys in this class.
