Answer:

x >
(-7)/(3) OR x > -2.33

Explanation:

The first step is to subtract 8 from both sides, like so:

-3x + 8 < 15

- 8 - 8

__________

-3x < 7

Divide both sides by -3:

x <
(-7)/(3)

Whenever, you multiply/divide by a negative number, you must flip the inequality sign around. In this case, we divided by a negative:

x >
(-7)/(3) OR x > -2.33
