solvefor x, 1/x-1/y-10=0

解答

求解

x, \frac{1}{x} - \frac{1}{y} - 10 = 0

x = \frac{y}{1 + 10 y}; y \neq = - \frac{1}{10}

求解步骤

\frac{1}{x} - \frac{1}{y} - 10 = 0

乘以最小公倍数

y - x - 10 x y = 0

将

y

到右边

- x - 10 x y = - y

分解

- x - 10 x y : - x (1 + 10 y)

- x (1 + 10 y) = - y

两边除以

- (1 + 10 y); y \neq = - \frac{1}{10}

x = \frac{y}{1 + 10 y}; y \neq = - \frac{1}{10}

\frac{5}{( \frac{( 6 - x )}{2} )} - \frac{x}{3} = 2 x + 4

∣ x ∣ + \frac{4 - x ^{2}}{x} = \frac{4}{x}

\frac{24}{20 + x} = \frac{24 + x}{44 + x}

so l v e f or x, f (x)^{- 1} = \frac{( 4 x - 3 )}{( x + 4 )}

so l v e f or x, \frac{15}{x} + y = 7
