Since you haven't shown any work on any of the questions you've posted, it would appear that you are in need of lessons. Unfortunately, we cannot reasonable provide the hours of instruction indicated. Sorry! :oops:

Fortunately, there are loads of great lessons available online!

. . . . .Google results for "solving linear equations"

Once you have studied one or more lessons and have learned the basic terms and techniques, please attempt this exercise. If you get stuck, please reply showing all of your work and reasoning so far. Thank you! :D

Tutoring sites tend to prefer to help students learn, in contrast to "cheetz" sites, which may post fully-worked solutions (though usually for a fee). To better utilize this site, it is generally wise to post representative exercises, rather than a flood of similar ones, and to show some effort of your own. Thank you!

12=-2(x+3)
12=-2x-6
12+6=-2x
18=-2x
18/-2=x
-9=x

you done good!
:D

fyi, you also could do it this way ...

12 = -2(x + 3)

divide both sides by -2 ...

-6 = x + 3

subtract 3 from both sides ...

-9 = x
