4 (1-x) > - 2 (1 + x) and 3 (3-x) ≤ 2 (x-1) - 4 to solve linear inequalities of one variable

4 (1-x) > - 2 (1 + x) and 3 (3-x) ≤ 2 (x-1) - 4 to solve linear inequalities of one variable

4(1-x)>-2(1+x) x《3
3 (3-x) ≤ 2 (x-1) - 4 x greater than or equal to 3

The solution of one variable linear inequality: X △ 3 ＞ = 1 - (X-2) △ 2

x÷3＞＝1-(x-2)÷2
2x>=6-3(x-2)
2x>=6-3x+6
5x>=12
x>=2.4

Solving the inequality of degree one variable (2x + 1) (X-5)

If 2x + 1 = 0, x = - 1 / 2
If X-5 = 0, then x = 5
The solution is - 1 / 2

How to express the solution set of 20% - 2 (x-1) > 11,2 (x-3) ≥ 3x-1 on the number axis

2-2x + 2 > 11, namely 2x

Solving the inequality of degree one variable, 2x + 13

2X+1

Solve the one variable linear inequality - 3 (X-2) is greater than or equal to 4-x, 3 / 1 + 2x > X-1

X ＞ - Four Thirds in one step

2x+1

2x+1

Finding positive integer solutions of one variable linear inequality 5 / 4 (x + 2) ≥ 2x-1

Double four on both sides
5x+10≥8x-4
3x≤14
x≤14/3
So x = 1, x = 2, x = 3, x = 4

4X & # 178; - 8x-15-3x & # 178; + 6x-2 = how much? It's better to have a formula

4x²-8x-15-3x²+6x-2
=4x²--3x²+6x-8x-15-2
=x²-2x-15-2
=x²-2x-17

(1) 4X = 5-2x (2) 4x = 6x-2 (3) 3x-4x-5 = 1 (4) - 3 / 4 x = 6-2 / 1 x

1、
6x=5
x=5/6
2、
2x-2=0
x=1
3、
-x=6
x=-6
4、
-3x/4=6-x/2
-x/4=6
x=-24
