#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#
