Question

(4x – 1)/3 < = (12x – 3)/7

Answer 1

Respuesta:

Explicación paso a paso:

(4x – 1)/3 < = (12x – 3)/7

$\frac{\left(4x-1\right)}{3}\le \frac{\left(12x-3\right)}{7}$

$\left(4x-1\right)\cdot \:7\le \:3\left(12x-3\right)$

$=28x-7$

$=36x-9$

$28x-7\le \:36x-9$

$28x-7+7\le \:36x-9+7$

$28x\le \:36x-2$

$28x-36x\le \:36x-2-36x$

$-8x\le \:-2$

$\frac{8x}{8}\ge \frac{2}{8}$

$x\ge \frac{1}{4}$
