As Cornel already had shown, you may use the symbolic "solve" to get all solutions.

In case you are only interested in real valued solutions, you may use an appropriate "assume" modifier:

Or if you are interested in the positive solution only, you may use

Apart from the symbolic "solve" you can also use a solve block with "find" or the "root" function.

If you evaluate symbolically, you will get all (real valued) solutions

If you evaluate numerically, you get just one solution depending on the interval you provide
