-3x less or equal to -4

$$\\-3x\le -4\\\\
$ divide both sides by -3 but remember that if you times or divide by a neg number you have to swap the sign around$\\\\
x\ge\frac{-4}{-3}\\\\
x\ge\frac{4}{3}\\$$

.

That depends very heavily on what x is.

 

If x is 4/3 than it is equal; otherwise any other positive number substituting x is less than.

 

If x is a negative number than it is greater than -4.
