I hope that everyone know that posting direct answers is against the Code of Conduct of Openstudy. :D

Anyway, if you want the steps, here's what you wanna do.

First, you add 7 on both sides.
\(-10x-7<13\) will become \(-10x-7+7<13+7\).

Combine like terms, and you'll get
\(-10x<20\)

Now, solve for x by dividing \(-10\) on both sides. Notice that you are dividing a NEGATIVE, so you must switch \(<\) to \(>\).
\[\frac{ -10x }{ -10 }>\frac{ 20 }{ -10 }\]

Answer 5

everyone knows***

Answer 6

Then \[x> 20 \div -10\]
