120=(180(n-2))/n

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

n = 6

Solution steps

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

Multiply both sides by

n

120 n = 180 (n - 2)

Expand

180 (n - 2) : 180 n - 360

120 n = 180 n - 360

Move

180 n

to the left side

- 60 n = - 360

Divide both sides by

- 60

n = 6

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = 6

\frac{6}{4 - 5 x} = \frac{2}{x}

\frac{4}{x ^{2}} = \frac{7}{x} + 2

x, u = \frac{y}{x}

4 x - 3 = \frac{5}{64 x ^{3} - 27 + 180 x}

\frac{25}{2601} = \frac{1}{4 c}
