Hi, there.
_____
Let us make n the subject of the equation (which is just a fancy name for "solve for n and find what it equals").
First off, add 360 to both sides:
[tex]\boldsymbol{S+360=180n}[/tex]
Next, divide both sides by 180:
[tex]\boldsymbol{\dfrac{S+360}{180}=n}[/tex] | n is now the subject of the equation.
Hope the answer - and explanation - made sense,
happy studying!!
