solvefor k,7-3m= 2/k

解答

求解

k, 7 - 3 m = \frac{2}{k}

k = \frac{2}{7 - 3 m}; m \neq = \frac{7}{3}

求解步骤

7 - 3 m = \frac{2}{k}

在两边乘以

k

7 k - 3 mk = 2

分解

7 k - 3 mk : k (7 - 3 m)

k (7 - 3 m) = 2

两边除以

7 - 3 m; m \neq = \frac{7}{3}

k = \frac{2}{7 - 3 m}; m \neq = \frac{7}{3}

0.083 = \frac{x ^{2}}{0.8 - 2 x}

x^{2} + (\frac{x}{x + 1})^{2} = 15

2 k = \frac{12}{k} - 5

3 = \frac{5}{a x} + 5

4 x^{- 4} - 7 x^{- 2} - 2 = 0
