Question

12-3(2x+3)≥2(3x-2)-5x

Answer 1

Respuesta: x≤1

Explicación paso a paso:

$12-3\left(2x+3\right)\ge \:2\left(3x-2\right)-5x$

$12-3\left(2x+3\right)= 12-6x-9= -6x+3$

$6x+3\ge \:x-4$

$-6x+3-3\ge \:x-4-3$

$-6x\ge \:x-7$

$-6x-x\ge \:x-7-x$

$-7x\ge \:-7$

$\left(-7x\right)\left(-1\right)\le \left(-7\right)\left(-1\right)$

$7x\le \:7$

$x\le \frac{7}{7}$

$x\le \:1$
