Solution inequality group 2 3x 2x 8 1 2 x 2 x 3 1 5

1 2-x>2-x 3 +1 is not clear, should you add a parenthesis or something, otherwise there is no solution.

Solution: 2+8<2x+3x

1/2-2-1>x-x/3

5x>10

2x/3<-5/2

So x>2 and x<-15 4

The answer to this question is that there is no solution.

2-3x<2x-8 1 2-x>2-x 3 +13x-2x<-8-2 The inequality is multiplied by 6 on both sides.

5x<-10 －6x+2x>12+6

x>2 -4x>18

x<-2/9

Because the group solution of inequality gives x>2 and x<-2 9, respectively

So there is no solution to this system of equations.

That's all there is to it.

2-3x<2x-8 can => x>2

1 (2-x)>(2-x) 3 +1 and x>2 can => x>(7 + root number 21) 2

The first two may not have understood the meaning of the question, and the questioner really didn't make it clear!

The solution is not equal to the Ming Pick-up Letter 2(x-1) 4-x, which is sold.

x 2, excite.

Solve inequality 3(x+1) 5x+7, get.

x -2, so the solution set of the inequality group is -2 x 2

1,6-x-x 0 becomes x +x-6 greater than or equal to 0, after the left decomposition factor, the two factors are greater than or equal to 0 at the same time or less than or equal to 0 at the same time, respectively, to form a system of equations, solution, other similar, the coefficient of the quadratic term is not 1, to be reduced to 1, 2, 1, (1) 6-x-x 0

x²+x-6≥0

x+3)(x-2) Fool Nomori 0

x≤-3，x≥2

2)x²+3x-4<0

x+4)(x-1)<0

4 -4 2, (with mu 1) 4x -27x+18 0, 4x-3) (x-6) >0

x "Spine which 3 4, x>6

2)x&..1,

Inequality one; -3x-1>3

Inequality two: 2x+1>3

x<-4/3

There is no solution to the x>1 inequality group.

Solution: 3x-2(9-x)>3(7+2x)-(11-6x) are obtained from the original formula.

3x-18+2x>21+6x-11+6x, i.e. 5x-18>10+12x

28>7x

Solution x 4

2(3x-1)-3(4x+5) x-4(x-7) is obtained from the original formula.

6x-2-12x-15 x-4x+28, i.e. -6x-17 -3x+28

45 3x solution x -15

So, the solution set for the group of inequalities is {x -15 x -4

1)x-5<1

Get x<6

2x>3

Get x>3 2

Because there is x<6

x>3/2

Therefore, use greater than small, (smaller than large to take the middle, that is, take the intersection).

Get 3 20 to launch 2x>5

Get x>5 2

Because there are 3-x<-1

x<-1-3

Introducing x>4(

Unknowns have a negative sign, and the inequality should be changed to a sign, i.e., greater than becomes less than, less than becomes greater than); And because 4>5 2

So x>4 (the same as the big takes the big, that is, the number axis takes the intersection of the inequality group).

Hello: 3 (x-2) + 8>2x

3x-6+8>2x

3x-2x>-2

x>-2

x+1/3≥x-x-1/2

x+1/3 ≥x-1/2x+1/2

x+1/3≥1/2x+1/2

x-1/2x≥1/2-1/3

1/2x≥1/6
