3/(3a+4)= 5/(5a-1)

解答

\frac{3}{3 a + 4} = \frac{5}{5 a - 1}

无解

求解步骤

\frac{3}{3 a + 4} = \frac{5}{5 a - 1}

使用分式交叉相乘

3 (5 a - 1) = (3 a + 4) \cdot 5

解

3 (5 a - 1) = (3 a + 4) \cdot 5 :

无解

无解

(\frac{24}{x + 0.7}) = 4

\frac{6 - X}{X} = \frac{4}{X + 1}

\frac{5}{x} = 12

\frac{15}{x} - 4 = \frac{2}{x}

\frac{5}{x - 7} = \frac{- 11}{2}
