Question

Решите неравенство: 2х-3> 5х
Решите неравенство: (х+1) + 2(х+1) + 3(х-1) < 4х + 3(х-2)

Answer 1

 2х-3> 5х 

3x<-3

x<-1

 

 

 

(х+1) + 2(х+1) + 3(х-1) < 4х + 3(х-2)

x+1+2x+2+3x-3<4x+3x-6

6x<7x-6

x>6

Answer 2

2х-5х>3

-3х>3

х>-1

(-1;+∞)

 

х+1+2х+2+3х-3<4х+3х-6

6х<7х-6

6<х

х>6

(6;+∞)
