$x < - 3$ $x<-3$

it is given

$- 4 x > 12$ $-4x>12$

So

$\Rightarrow 4 x < - 12$ $=> 4x<-12 " "$ [ $\div$ $div$ by a negative $\to$ $->$ flip the sign]

$x < \frac{- 12}{4} \Rightarrow x < - 3$ $x< (-12)/4 => x<-3$

so the solution of this question is $x < - 3$ $x<-3$ .

$x < - 3$ $x<-3$

Given: $- 4 x > 12$ $-4x>12$ .

Divide by $4$ $4$ on both sides.

$\frac{- 4 x}{4} > \frac{12}{4}$ $(-4x)/4>12/4$

$- x > 3$ $-x>3$

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

$\Rightarrow x < - 3$ $=>x<-3$
