What is 2x-1= i need the steps and stuff

Here's all the inside stuff.  It may get complicated,
but I'll go slow, so try to follow me.

2x - 1 = 7

Step #1:
Add 1 to each side:

2x = 8

Step #2:
Divide each side by 2 :

x = 4


Where have you been all semester ?

2x-1=7
-1 -1

2/8
4
I wish that is right
