x=16

Explanation:

Let's start by adding 15 to both sides to get:

6x=80+x

We can subtract x from both sides to get:

5x=80

Lastly, we can divide both sides by 5 to get:

x=16

x = 16

Explanation:

To figure out any problem with only one variable at this level of math, you usually always bring all you're x's on one side and your regular numbers (constants) on the other side.

If you add 15 to both sides you can bring the 15 on the right side to get

6x = 80 + x

Now you need to bring the x on the left-hand side. We can do this by subtracting it on both sides.

Now we have

5x = 80

Divide by 5 on both sides to get

x = 16
