Question

8. 1)
(4(x + 1) > 3(x + 3) - x,
2(2x - 1) > 7(x + 1);
(4(x + 1) <3(x-3) - x,
2)
14(2x - 1)<3(3x - 2).СРОЧНО​

Answer 1

Ответ:

1) (4(х+1)>3(х+3)-х,

4х+4>3х+9-х,

4х-3х+х>9-4,

2х>5,

х>2/5.

2(2х-1)>7(х+1), 4х-2>7х+7, 4х-7х>7+2,

-3х>9|÷(-3), х<-3.

(4(х+1)<3(х-3)-х, 4х+4<3х-9-х, 4х-3х-х<-9-4,

4х-4х<-13, х<-13.

14(2х-1)<3(3х-2), 28х-14<9х-6, 28х-9х<-6+14, 19х<8, х<8/19.
