5/(-3+3)+2/(-3^2-9)= 4/(-3-3)

解答

\frac{5}{- 3 + 3} + \frac{2}{- 3 ^{2} - 9} = \frac{4}{- 3 - 3}

假

求解步骤

\frac{5}{- 3 + 3} + \frac{2}{- 3 ^{2} - 9} = \frac{4}{- 3 - 3}

化简

\frac{5}{- 3 + 3} + \frac{2}{- 3 ^{2} - 9} :

未定义

化简

\frac{4}{- 3 - 3} : - \frac{2}{3}

未定义 = - \frac{2}{3}

因此

假

\frac{9 - x}{2} = 13

9 x + 2 = 7 x + 18

\frac{1}{5} c - \frac{5}{6} = \frac{4}{5} c + \frac{1}{2}

2 x - 1 = - 7

\frac{5 x}{3} - 1 = \frac{x}{8} - \frac{1}{10}
