Solve the solution equation. Solve equations and solve them.

1.You don't need to turn it into fractions, just forget it. It's the same with melting. x=2.Add 3 to both sides at the same time to get 3x=4 x=4 3

3.Multiply both sides by 6 at the same time to get 4x+2=5x-1 subtract 4x from both sides at the same time to get 2=x-1 and add 1 to both sides at the same time to get x=3

4.Multiply both sides by 2x+6 at the same time to get 4x+(2x+6)=7 remove the brackets to get 6x+6=7 Subtract 6 from both sides at the same time to get 6x=1 x=1 6

6/a^20)-a= ( 6/a^20)-a^21/a^20=(6-a^21）/a^20

6.I don't see a u in this question.

1）3x+

3+x=32）3x-3=1

3x=4x=4/3

3）（4x+2）/6=(5x-1)/6

Multiply both sides by 6, 4x+2=5x-1

4x-5x=-1-2

Merge items of the same kind.

Get -x=-3

Divide both sides by -1 to get x=3

4）(4x/2x+6)+1=7/2x+6

Multiply both sides by 2x+6 to get 4x+2x+6=7

Move items to get 4x+2x=7-6

Merge similar terms to get 6x=-1

Divide both sides by 6 to get x=-1 6

5）(a-1/a^2)+2=[(a-1)+2a^2]/a^26/a^20)-a=(6-a*a^20)/a^20=(6-a^21)/a^20

6）4x^3y+12x^2y^2+9xy^3 / 4x^3-9xy^3

xy(4x^2+12xy+9y^2)

xy(2x+3y)^2

When x=1, y=1, the original formula = 25

1）3x+

x=52）3x-3=1

3x=4x=4/3

3) Multiply both sides by 6 at the same time to remove the denominator Original formula 4x+2=5x-1 4x-5x=-1-2 -x=-3 x=3

4) Original formula 2+7=7 2x+6 7 2x=3 6x=7 x=7 65) The denominator becomes the square of a A 3 A 2-A 2+2A 2 A 2 A 2 I played the sixth question too troublesomely.

The first is 5 and the second you are right and the third ... The fourth... The fifth... The sixth one I don't understand, in fact, you can't read it at all on the computer.

This topic is the calculation of a one-dimensional equation, and the detailed process is as follows:

8x÷3+5=x+7,8x/3+5=x+7,8x/3-x=7-5,<>

The process of this question is as follows:

Left = 8x 3 + 5 = 8 * 6 5 3 + 5 = 16 5 + 25 5 = 41 5, right = x + 7 = 6 5 + 7 = 6 5 + 35 5 = 41 5, left = right, i.e. x = 6 5 is the solution of the equation.

Knowledge Expansion: A one-dimensional equation is an equation that contains only one unknown, the highest order of the unknown is 1, and both sides are integers. There is only one root of the unary equation, and the unary equation can solve most of the engineering problems, travel problems, distribution problems, profit and loss problems, integral table problems, billing problems, and number problems.

Geometric Significance of Unary Linear Equations:

Since unary linear functions can be converted into the form of ax+b=0 (a, b is constant, a≠0), solving a unary linear equation can be transformed into finding the value of the corresponding independent variable when the value of a function is 0. From the image, this is equivalent to finding the value of the abscissa of the intersection point of the pure line y=kx+b (k, b is a constant, and k≠0) is the intersection point.

The solution of the equation is x = 3. The process of solving the equation is as follows:

First, we get 2(2x+1) 6-(x-1) 6=2, and obtain: (4x+2) 6-(x-1) 6=2 and merge similar terms to obtain: (3x+3) 6=2

Multiply both sides of the equation by 6 at the same time, yielding: 3x+3=12

Move items and merge similar items to get: 3x=9

Divide both sides of the equation by 3 at the same time, yielding: x=3

Hello: 15 2 18 5x=18 25 multiplied by 50375-90x=36

90x=375-36

90x=339

x=339÷90

x=113/30

19/5×21/5－4x=139/25

399/25-4x=139/25

Good luck with your studies!

One question. 15/2－18/5x=18/25

Multiply both sides by 50 to get.

375-180x=36

180x=339

x=339/180

x=113/60

Two questions. 19 5 21 5 4x=139 25 multiply 25 by 25 on both sides.

399-100x=139

100x=260

x = three questions. 3 5x+11 4=4 and 11 20

Multiply both sides by 20 to get.

12x+55=91

12x=36

x=3. 8x-12x1 10=18 5 multiply both sides by 10 to get.

80x-12=36

80x=48x=

In the eighth round, Lin Jiao's head thorn was matched with Cangzhou Road, and Lu Zhishen made a big fuss in the wild boar forest.

3/7x＝15，x＝35………The solution idea, there are a total of x kilograms (total amount), divide x kilograms into 7 parts, the weight of 3 of which is 15 kilograms, and find the total amount x.
