Tìm x: a) 1-(5\(\frac{3}{8}\)+x-7\(\frac{5}{24}\)):16\(\frac{2}{3}\)=70

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

c)\(\frac{x}{-2}=\frac{-8}{x}\)

Tìm x, biết 

A.\(\left(-1\frac{1}{5}+x\right):\left(-3\frac{3}{5}\right)=-\frac{7}{4}+\frac{1}{4}:\frac{11}{8}\)

B.\(7,5x:\left(5\frac{195}{315}-8\right)=2\frac{13}{15}\)

C.\(60\%x+\frac{2}{3}x+x=688\)

D.\(1-\left(5\frac{3}{8}-x-7\frac{5}{24}\right):16\frac{2}{3}=0\)

Tìm x biết \(1\frac{1}{30}:\left(24\frac{1}{6}-24\frac{1}{5}\right)-\frac{1\frac{1}{2}-\frac{3}{4}}{4x-\frac{1}{2}}=\left(-1\frac{1}{15}\right):\left(8\frac{1}{5}-8\frac{1}{3}\right)\)

Tìm x biết:\(1-\left(3\frac{3}{8}+x-2\frac{5}{24}\right)\cdot\frac{12}{17}=0\)

Tìm x biết \(1\frac{1}{30}:\left(24\frac{1}{6}-24\frac{1}{5}\right)-\left(1\frac{1}{2}-\frac{3}{4}\right):\left(4x-\frac{1}{2}\right)=\left(-1\frac{1}{15}\right):\left(8\frac{1}{5}-8\frac{1}{3}\right)\)

Tìm x:

\(-\frac{5}{17}+\frac{3}{17}\le\frac{x}{17}\le\frac{13}{17}+-\frac{11}{17}\)

\(\frac{5}{6}+-\frac{7}{8}\le\frac{x}{24}\le-\frac{5}{12}+\frac{5}{8}\)

\(\frac{8}{17}+\frac{5}{17}< \frac{x}{17}< \frac{6}{17}+\frac{9}{17}\)

\(-\frac{6}{7}+\frac{3}{35}< \frac{x}{35}\le-\frac{2}{5}+\frac{3}{7}\)
