x 1 5 x 3 5 10 how to write the process

Solution: Multiply both sides of the equation by removing the denominator.

i.e. 5x = 15

x=15×

First, the decimal is converted into a fraction x to 2x 3+2x 7=10, and then the general fraction is 14x 21+6x 21=10

Simplify 20x 21=10 to get x=21 2

Multiply both sides of the equation at the same time to get: 7x+3x=105

i.e. 10x=105 then x=

Multiply by 21 at the same time, and in and the same term, you get.

Solution: 2x= Root type positive according to the silver rent: divisor.

The dividend quotient 2x 2= according to the nature of the equation: both sides of the equation are divided by the front 2 x=

This time divide 2= multiply both sides of the formula by Zao Xiangsheng 2, that is, it becomes x=, and the result comes out, and Lu Laoyan is the simplest unary equation problem.

In the case of a one-dimensional equation, you can think of it this way, what number divided by 2 is equal to, then it can be multiplied by 2 that the value of this x is equal to 9

According to the number of the trapped people who are removed by the brigade stove = quotient divisor, it can be known that x=2, so x=9. The process is as follows.

x÷2=x=x=9

Solution: 2x= according to: the number of the devoid = the number of the detrimental 2x 2= according to the nature of the equation: both sides of the equation are divided by 2 x=

Question (x also = 2x-5???I guess there should be two answers.

Solution: Remove the brackets.

12x-4=2x+5

Move to the to. 12x-2x=5+4

Mergers of the same kind.

10x = 9 coefficient of posture 1.

x=9/10

Solution: Remove the brackets.

12x-4=2x-5

Shift and deteriorate.

12x-2x=-5+4

Mergers of the same kind.

10x=-1

The coefficient of 1 has to be marked.

x=-1/10

If you understand, please ask.

4:3=:( a x).

3*4x=x=2÷4

Friend, please [adopt the answer], your adoption is the motivation for me to answer the question, if you don't understand, please ask. Thank you.

Solution: (first expand the numerator denominator by 10 times by the fraction containing the decimal of Zen Zhengchang Cong Stool, and then remove the denominator) 1) Expand the fraction containing the decimal by 10 times to obtain: (12-20x) 2-(15-25x) 5=(3x-5) 4+1 2

3-5x)=(3x-5)/4+1/2；i.e.: 3-5x=(3x-5) 4+1 2

Remove the denominator to get: 4 (3-5x) = 3x-5 + 2, i.e.: 23x = 15 So, x = 15 23
