How to solve for x in an sin equation?

Hi MATLAB wizards
I am currently trying to solve the following equation; -7sin(x/7)=0 using symbolic algebra and the solve function in MATLAB.
The code that I used is as follows:
syms x
solve( (-7*sin(x/7)),x)
This code returns the value 0, which is one of the solutions, the other one is 7*pi.
So how can I produce both of these solutions?
Any form of help would be appreciated.

No. There are INFINITELY many solutions. So you cannot say you want the OTHER solution. You can simply enough find a positive solution though.
syms x positive
solve( (-7*sin(x/7)),x)
ans =
7*pi
