Apr 30, 2018

$x < - 3$

#### Explanation:

it is given

$- 4 x > 12$

So

$\implies 4 x < - 12 \text{ }$ [$\div$ by a negative $\to$ flip the sign]

$x < \frac{- 12}{4} \implies x < - 3$

$x < - 3$

#### Explanation:

Given: $- 4 x > 12$.

Divide by $4$ on both sides.

$\frac{- 4 x}{4} > \frac{12}{4}$

$- x > 3$

Switch signs. That means that the inequality sign flips as well.

$\implies x < - 3$
