(n!)/((n-2)!)=240

\frac{n !}{( n - 2 ) !} = 240

n = 16, n = - 15

Solution steps

\frac{n !}{( n - 2 ) !} = 240

Simplify

\frac{n !}{( n - 2 ) !} : n (n - 1)

n (n - 1) = 240

Solve

n (n - 1) = 240 : n = 16, n = - 15

n = 16, n = - 15

\frac{3}{2 x - 4} = 0.5

\frac{2 x - 1}{3} = \frac{1}{5 - x}

x, \frac{2}{x} - \frac{3}{y} = 9

(\frac{( x ^{1} ) ^{2} + 1}{( x ^{1} ) ^{2}}) = 8

\frac{7.2}{x + 2} = \frac{x - 2}{3.2}
