In this problem, we're going to solve a one -step equation for the variable x.
00:05
We're going to solve this by using the multiplication property of quality.
00:10
Now, the multiplication property of equality basically means that when you multiply one side by a number, you have to multiply the other side by that same number.
00:19
So we're going to go ahead and, first of all, we see this division of two, and we see this negative out front.
00:26
I'm going to go ahead and move this negative to the bottom of the fraction with the two as a negative two.
00:32
Now, because we're divided by negative 2, we have to do the opposite, which is to multiply by negative 2.
00:38
This is the inverse operation.
00:41
When we're doing this, basically dividing by negative 2 and multiplied by negative 2 are opposites...
