2x - 12 = 14

Add 12 to both sides of the = sign to get rid of the "-12".

2x - 12 + 12 = 14 + 12
2x = 26

Now divide both sides by 2 to isolate the x

2x / 2 = 26 / 2
x = 13.

The solution is x = 13.

Hope this helps!

Let me know if there's anything you're still confused about and I'll try to help you out.

Solving for x like this is definitely something you want to master and be able to do on your own, because you'll be doing it in future math.
