Tìm x biết:

a)\(\frac{3}{5}\times x-\frac{1}{5}=\frac{4}{5}\)

b)\(\frac{4}{7}+\frac{5}{7}\div x=1\)

c)\(\frac{-12}{7}\times\left(\frac{3}{4}-x\right)\times\frac{1}{4}=-1\)

d)\(x\div\frac{17}{8}=\frac{-2}{5}\times\frac{-9}{17}+3\)

Bài 1 : Tìm x biết

a) \(13\frac{1}{3}\div1\frac{1}{3}=26\div\left(2x-1\right)\)

b) \(0,2:1\frac{1}{5}=\frac{2}{3}\div\left(6x+7\right)\)

c) \(\frac{37-x}{x+13}=\frac{3}{7}\)

d) \(\frac{x-1}{x+5}=\frac{6}{7}\)

e) \(2\frac{2}{\frac{3}{0,002}=}\frac{1\frac{1}{9}}{x}\)

Bài 2 : Tìm x,y,z biết:

a) \(\frac{x}{7}=\frac{4}{13}\)và x + y = 40

b) 3x = 2y , 7y = 57 và x - y + z = 32

c) \(\frac{x-1}{2}=\frac{y-2}{3}=\frac{7-4}{4}\)và 2x + 3y - z = 50
Bài 3 .

a) 6,88 : x =12:27

b) \(8\frac{1}{3}\div11\frac{2}{3}=13:\left(2x\right)\)
