Tìm số nguyên x biết :

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

b) \(\frac{-x}{4}\) = \(\frac{-9}{x}\)

c) \(\frac{-35}{7}\) < x \(\le\) -1

d) \(\frac{-30}{5}\) < x < \(\frac{-45}{9}\)

Tìm số nguyên x, biết : 

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

b) \(\frac{-x}{4}\) = \(\frac{-9}{x}\)

c) \(\frac{-35}{7}\) <  x < -1

d) \(\frac{-30}{5}\) < x < \(\frac{-45}{9}\)

Tìm số nguyên x

a) \(\frac{1}{3}+\frac{-2}{5}+\frac{1}{6}+\frac{-1}{5}\le x< \frac{-3}{4}+\frac{2}{7}+\frac{-1}{4}+\frac{3}{5}+\frac{5}{7}\)

b)\(\frac{5}{17}+\frac{-9}{4}+\frac{-26}{31}+\frac{12}{17}+\frac{-11}{31}< \frac{x}{9}\le\frac{-3}{7}+\frac{7}{15}+\frac{4}{-7}+\frac{8}{15}\)

Bài 8: Tìm số nguyên x biết

a) \(\left(\frac{-12}{27}+\frac{2}{3}\right)+\frac{-2}{9}\le x\le\left(\frac{11}{7}+\frac{2}{5}\right)+\frac{7}{5}+\frac{3}{7}\)                       b\(\frac{-x}{2}+\frac{2x}{3}+\frac{x+1}{4}+\frac{2x+1}{6}=\frac{8}{3}\)

c)\(\frac{3}{2x+1}+\frac{10}{4x+2}-\frac{6}{6x+3}=\frac{12}{26}\)

Tìm tập hợp các số nguyên x biết:

\(a,4\frac{5}{9}:2\frac{5}{8}-7< x< \left(3\frac{1}{5}:3,2+4,5.1\frac{31}{45}\right):\left(-21\frac{1}{2}\right)\)

\(b,\frac{-17}{21}:\left(\frac{5}{4}-\frac{2}{5}\right)< x+\frac{4}{7}< 1-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}\)

Giúp mik nha! Ai làm đc mik cho 3 tick!
