Question

What is the answer to: -1.5x -3.1 < 5.5

Answer 1

For this case we have the following expression:

$-1.5x-3.1$

Adding 3.1 to both sides of the inequality:

$-1.5x$

Dividing between -1.5 on both sides of the inequality, keeping in mind that the sign changes direction:

$x> \frac {8.6} {- 1.5}\\x> -5.73333$

Answer:

$x> -5.73333$
