138=(180(n-2))/n

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

n = \frac{60}{7}

Decimal Notation

n = 8.57142 \dots

Solution steps

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

Multiply both sides by

n

138 n = 180 (n - 2)

Expand

180 (n - 2) : 180 n - 360

138 n = 180 n - 360

Move

180 n

to the left side

- 42 n = - 360

Divide both sides by

- 42

n = \frac{60}{7}

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = \frac{60}{7}

\frac{81.1}{2.47} = \frac{59}{b}

0.75 = \frac{19600}{x} \cdot 100

0.3 = \frac{x}{x + 114}

\frac{( 3 x - 4 )}{x + 2} = 0

y = \frac{36}{2 y}
