I need to solve S=180n-360 for n and need to show work. Help
S = 180n - 360
S+360 = 180n -360+360 = 180n
(S+360)/180 = 180n/180 = n
S/180 + 2 = n
To solve the equation S = 180n - 360 for n, you need to isolate the variable n on one side of the equation. Here's how you can do it step by step:
Step 1: Start with the given equation: S = 180n - 360.
Step 2: In order to isolate n, you need to get rid of the -360 on the right side of the equation. You can do this by adding 360 to both sides of the equation:
S + 360 = 180n - 360 + 360.
Step 3: Simplify the equation:
S + 360 = 180n.
Step 4: To further isolate n, divide both sides of the equation by 180:
(S + 360) / 180 = (180n) / 180.
Step 5: Simplify the equation:
(S + 360) / 180 = n.
Step 6: Rearrange the equation to have n on the left side:
n = (S + 360) / 180.
Thus, the solution to the equation S = 180n - 360 is n = (S + 360) / 180.

Just recall that your goal is to get "n" all by itself on one side of the equation. To do that, collect all the "n" stuff on one side, and all the numbers on the other.
Key: If an equation is true, then it remains true as long as you do the same thing to both sides of the equation.
S = 180n - 360
S+360 = 180n -360+360 = 180n
(S+360)/180 = 180n/180 = n
S/180 + 2 = n
