Answer:

n =-19

Step-by-step explanation:

3* (n+7) = -36

Distribute

3n+21 = -36

Subtract 21 from each side

3n+21-21 = -36-21

3n = -57

Divide by 3

3n/3 = -57/3

n =-19

How do I do this?<br> 4/5x&gt;14
Likurg_2 [28]

Well, first, you need to know what you want to 'do' to it.

You want to find the description of what 'x' has to be in order to
make that inequality a true statement.  Here's one way to do it:

                                              4/5 x > 14

Multiply each side by  5 :     4    x  >  70

Divide each side by  4 :             x  >  17.5 .

That's it.  As long as 'x' is more than 17.5 ,
the original inequality is true.
