This is a review question.

It's solving a linear equation asking us to solve for the variable x.
00:07
So i'm going to solve this a way that will work for any time you have distribution, and that is to distribute this four inside the group first.
00:20
So i'm going to be left with then 4x, 4 times x is 4x, 4 times 2 is 8, and i'll be subtracting, right? so it becomes 4x minus 8 equals 3x plus 5.
00:33
So you can think of this as a balance scale.
00:35
So i always split my equation to show my left side and my right side.
00:39
And what i do to one side i have to do to the other side.
00:42
So right now we have variables on both sides.
00:45
And what makes sense when you're solving for a variable is to get all your variables to one side, all your constants to others.
00:52
So you can move either one you want.
00:54
If you move the lesser variable, you will be dealing with positive variable...
