((n-2)180)/n =108

\frac{( n - 2 ) 180}{n} = 108

n = 5

Solution steps

\frac{( n - 2 ) \cdot 180}{n} = 108

Multiply both sides by

n

180 (n - 2) = 108 n

Expand

180 (n - 2) : 180 n - 360

180 n - 360 = 108 n

Move

360

to the right side

180 n = 108 n + 360

Move

108 n

to the left side

72 n = 360

Divide both sides by

72

n = 5
