How to solve the linear equation of one variable whose denominator is decimal For example: (2x + 1) / 0.02 - (3-x) / 0.1 = 1 plus text,

First, expand the numerator denominator by 10 times, 100 times and 1000 times at the same time. Change the fraction whose denominator is a decimal into a fraction whose denominator is a positive number. Then, solve it according to the general method of solving equations. For example: (2x + 1) / 0.02 - (3-x) / 0.1 = 1 step 1, expand the numerator and denominator of (2x + 1) / 0.02 by 100 times at the same time, get 100 (2x + 1) / 2 step 2

Calculate (x * x + 4x + 5) / (x + 2) - (x * x + 6x + 10) / (x + 3) + 1
Molecular factorization
(x² + 4x + 4 +1) / (x+2) - (x² + 6x +9 +1)/(x+3) + 1
= [(x+2)² +1] / (x+2) - [(x+3)² + 1]/(x+3) + 1
= (x+2) + 1/(x+2) - (x+3) - 1/(x+3) + 1
= 1/(x+2) - 1/(x+3)
= [(x+3) - (x+2)] / (x+2)(x+3)
= 1 / (x+2)(x+3)
How to solve the equation 3x + 5 = 10x-7
3X+5=10X-7
10X-3X=5+7
7X=12
X=12/7
3X+5=10X-7
12=7x
x=12/7
What grade are you in? primary school? junior middle school? Have you ever learned to shift the term? Put the term with X on the right, combine it with multiplicative binding rate, and move the constant (that is, natural number) to the left to get 7x = 12, x = 12 / 7
3x+5=10x-7
7x=12
x=12/7
2x-6x + 12 = 14-12x + 24-4x how much is x = by equation
2x-6x + 12 = 14-12x x x 24-4x
-4X+12=38-16X
12X=26
X=13/6
X = 13 / 6
Solving equation 3x ^ 2-10x + 3
Finally, is it = 0, that is, 3x ^ 2-10x + 3 = 0
Pre factorization
3x^2-10x+3=(3x-1)*(x-3)=0
obtain
X = 1 / 3 or x = 3
3x^2-10x+3=0
(3x-1)(x-3)=0
3x-1 = 0 or x-3 = 0
X = 1 / 3 or x = 3
Calculation process of X-1 / 4x = 3 / 8 (equation)
X－1/4X＝3/8
（1-1/4）X=3/8
3/4X=3/8
X=3/8÷3/4
X=3/8×4/3
X=1/2
Multiply left and right by 4 to make 4x-x = 3 / 4 3x = 3 / 2 x = 1 / 2
The formula method is used to connect the following equation: 3x times x-7x + 1 = 0, 12x times x-8x-21 = 0
1.3x times x-7x + 1 = 0
x^2-7/3 x=-1/3
(x-7/6)^2=49/36 -1/3
x =7/6±√37/6
2.12x times x-8x-21 = 0
x^2-3/4 x=7/4
(x-3/8)^2=7/4 +9/64
x=3/8±11/8 x1=-1,x2=7/4

It is known that the solution of the equation 4x + 2K = 3x + 1 is the same as that of the equation 3x + 2K = 6x + 1. Find the value of K
4x+2k=3x+1
4x-3x=1-2k
x=1-2k
3x+2k=6x+1
6x-3x=2k-1
3x=2k-1
x=（2k-1）/3
Because the solutions are the same
So 1-2k = (2k-1) / 3
3-6k=2k-1
2k+6k=1+3
8k=4
k=1/2
4x+2k=3x+1
x=1-2k ①
x+2k=6x+1
5x=2k-1 ②

5（1-2k）=2k-1
k=1/2
From 4x + 2K = 3x + 1 we get x = 1-2k
From 3x + 2K = 6x + 1 we get 3x = 2k-1, so x = (2k-1) / 3
Because the solutions are the same, 1-2k = (2k-1) / 3
So 3-6k = 2k-1
8k=4
k=1/2
So the value of K is 1 / 2
From 4x + 2K = 3x + 1
x=1-2k
From 3x + 2K = 6x + 1
3x-6x=1-2k
-3x=1-2k
x=(1-2k)/3
Because the solutions of the two equations are the same
So 1-2k = (1-2k) / 3
3-6k=1-2k
-4k=-2
k=1/2
3x plus 2 times 3.6 is 21.6, which is the equation
3x+2*3.6=21.6
3x+7.2=21.6
3x=21.6-7.2
3x=14.4
x=14.4/3
x=4.8
3x=14.4
