Question

1/5 -2 [x+1]≤0 ayuda nececito resolver esta ecuación para hoy​

Answer 1

Respuesta:

$x\ge \:-\frac{9}{10}$

Explicación paso a paso:

1/5 -2 [x+1]≤0

$\frac{1}{5}-2\left[x+1\right]\le \:0\\\\-10x-9\le \:0\\\\-10x-9+9\le \:0+9\\\\-10x\le \:9\\\\\left(-10x\right)\left(-1\right)\ge \:9\left(-1\right)\\\\10x\ge \:-9\\\\\frac{10x}{10}\ge \frac{-9}{10}\\\\x\ge \:-\frac{9}{10}$
