Question

помогите как решить систему неравенств
x+2.6≤0
x+5≥1

Answer 1

{x<=-2,6,
{x>=-4.
x принадлежит интервалу [-4;-2,6]

Answer 2

$\left \{ {{x+2.6 \leq 0} \atop {x+5 \geq 1}} \right. \\ \\ \left \{ {{x \leq -2.6} \atop {x \geq 1-5}} \right. \\ \\ \left \{ {{x \leq -2.6} \atop {x \geq -4}} \right. \\ \\ -4 \leq x \leq -2.6 \\ \\ x\in[-4;-2.6]$
