(180(n-2))/n =12

\frac{180 ( n - 2 )}{n} = 12

n = \frac{15}{7}

Decimal Notation

n = 2.14285 \dots

Solution steps

\frac{180 ( n - 2 )}{n} = 12

Multiply both sides by

n

180 (n - 2) = 12 n

Expand

180 (n - 2) : 180 n - 360

180 n - 360 = 12 n

Move

360

to the right side

180 n = 12 n + 360

Move

12 n

to the left side

168 n = 360

Divide both sides by

168

n = \frac{15}{7}

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = \frac{15}{7}

\frac{1}{x + 1} + \frac{1}{x + 2} = 0

1 = \frac{12 x ^{2}}{x ^{4} + 36}

- \frac{2}{9} = \frac{5}{x}

20 - \frac{7}{x} = 2 x

\frac{12 + 13 x}{4 x} = x
