Answer:
x = 4
Explanation:
So, the basic way that we solve a one variable equation is isolating the x variable on one side. We can see that we have a -9 on the left side, and a -1 on the right. Let's simplify this to isolate the x variable:
First, add 9 to both sides:
2x=8
Now, we can divide both sides by 2:
x = 4
Remember when doing these solving for x problems:
Whatever you do to one side, you have to do to the other
