Can you solve an equation and explain each step?

Lets do a simple two step equation

For example, 

2x-8=12

Our main goal is to get the X value alone.

In order to do this, We will subtract 8 from both sides.

Our equation will now look like:

2x=20

In order to get the X alone here, We have to divide 2x by 2 in order to cancel out the 2 out. This means that since we divided by 2 on one side, we have to do it on the other. 

Our equation now looks like:

x=10
