How to solve your problem
(−2)⋅180=⋅135
(n-2) \cdot 180=n \cdot 135(n−2)⋅180=n⋅135
Solve
1
Re-order terms so that constants are on the left
(−2)⋅180=⋅135
(n-2) \cdot {\color{#c92786}{180}}=n \cdot 135(n−2)⋅180=n⋅135
180(−2)=⋅135
{\color{#c92786}{180}}(n-2)=n \cdot 135180(n−2)=n⋅135

Re-order terms so that constants are on the left
180−360=⋅135
180n-360=n \cdot {\color{#c92786}{135}}180n−360=n⋅135
180−360=135
180n-360={\color{#c92786}{135}}n180n−360=135n

Add
360
360360
to both sides of the equation
180−360=135
180n-360=135n180n−360=135n
180−360+360=135+360
180n-360+{\color{#c92786}{360}}=135n+{\color{#c92786}{360}}180n−360+360=135n+360

Simplify
Add the numbers
180−360+360=135+360
180n{\color{#c92786}{-360}}+{\color{#c92786}{360}}=135n+360180n−360+360=135n+360
180=135+360
180n=135n+360180n=135n+360
180=135+360
180n=135n+360180n=135n+360

Subtract
135
135n135n
from both sides of the equation
180=135+360
180n=135n+360180n=135n+360
180−135=135+360−135
180n{\color{#c92786}{-135n}}=135n+360{\color{#c92786}{-135n}}180n−135n=135n+360−135n
