c= pi/x

解答

c = \frac{π}{x}

x = \frac{π}{c}; c \neq = 0

求解步骤

c = \frac{π}{x}

在两边乘以

x

c x = π

两边除以

c; c \neq = 0

x = \frac{π}{c}; c \neq = 0

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

\frac{6}{y + 2} + \frac{1}{y - 2} = 1

so l v e f or n, \frac{n + 7}{n - 4} = 2 s

\frac{2 k + 1}{k - 3} = \frac{2}{5}

\frac{3 x}{x ^{2} + 5 x - 1} = 0
