x=16x=16

Explanation:

Let's start by adding 1515 to both sides to get:

6x=80+x6x=80+x

We can subtract xx from both sides to get:

5x=805x=80

Lastly, we can divide both sides by 55 to get:

x=16x=16

x = 16x=16

Explanation:

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

If you add 1515 to both sides you can bring the 1515 on the right side to get

6x = 80 + x6x=80+x

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

Now we have

5x = 805x=80

Divide by 5 on both sides to get

x = 16x=16
