solvefor x,f= 4/x f(0)

解答

求解

x, f = \frac{4}{x} f (0)

x = \frac{4 f ( 0 )}{f}; f \neq = 0

求解步骤

f = \frac{4}{x} f (0)

化简

\frac{4}{x} f (0) : \frac{4 f ( 0 )}{x}

f = \frac{4 f ( 0 )}{x}

在两边乘以

x

f x = 4 f (0)

两边除以

f; f \neq = 0

x = \frac{4 f ( 0 )}{f}; f \neq = 0

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

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

10 = \frac{30}{0.02 x ^{2} + 1}

\frac{1}{6 x} = 9

so l v e f or c, f = \frac{c}{c - e}
