помогите пожалуйста ​

Answer 1

Ответ:

1) $x<-2$

2) $x>-3$

Пошаговое объяснение:

1)

$left { {{2(x+5)<2-2x} atop {3(2-x)geq 3-x}} right. \left { {{2x+10<2-2x} atop {6-3xgeq 3-x}} right. \left { {{2x+2x<2-10} atop {x-3xgeq 3-6}} right. \left { {{4x<-8} atop {-2xgeq 3}} right. \left { {{x<-2} atop {xleq -1,5}} right. \x<-2$

2)

$left { {{3(x+8)>9-2x} atop {3(x+4)geq x+5}} right. \left { {{3x+24>9-2x} atop {3x+12geq x+5}} right. \left { {{3x+2x>9-24} atop {3x-xgeq 5-12}} right. \left { {{5x>-15} atop {2xgeq -7}} right. \left { {{x>-3} atop {xgeq -3,5}} right. \x>-3$
