Question

s=(n-2)180 solve for n

Answer 1

distribute the 180: 180n - 360 = s

Add 360 to both sides: 180n = s + 360

Divide both sides by 180: n = (s+360)/180

Answer 2

thank you. I thought it was n=s+2 but based on this you are saying the s+360 are over the 180 and you cannot break that down further?

Answer 3

The equation could be written n = (s/180) + (360/180)

n = (s/180) + 2 but NOT (n =s + 2)<---bad

Answer 4

thank for your help

Answer 5

No problem if you get confused you can always try out numbers:

Say s = 2

does (2 + 360)/180, 362/180 equal 2 + 2? no way

So it is very easy to check if your confused
