Answer 1

Respuesta:

$x \leq 7$

Explicación paso a paso:

$x+\dfrac{8}{4}\geq 2x-5\\\\\\x+\dfrac{8}{4}-\dfrac{8}{4}-2x\geq 2x-5-\dfrac{8}{4} -2x\\\\\\-x \geq -\dfrac{20}{4}-\dfrac{8}{4} \\\\\\-x \geq \dfrac{-20-8}{4} \\\\\\-x \geq \dfrac{-28}{4} \\\\\\-x \geq -7 \\\\\\-x *(-1)\leq -7*(-1)\\\\\\x\leq 7$
