Answer 1

Ответ:

1) $x<-2$

2) $x>-3$

Пошаговое объяснение:

1)

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

2)

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