Answer:

x < -7

Step-by-step explanation:

-6x > 42

First you want to divide off -6 to isolate x

[tex]\frac{-6x}{-6}[/tex] = [tex]\frac{42}{-6}[/tex]

keeping in mind what you do to one side of the equation you have to do to the other side.

Whenever you divide with a negative number the inequality sign flips from < to > and vice versa.

after you divide off the -6 your left with x < [tex]\frac{42}{-6}[/tex] which equals -7.

Hope this helps.
