Bài 17: Tìm x \(\in\)Z biết:
\(\frac{2}{3}\times\left(\frac{1}{2}+\frac{3}{4}-\frac{1}{3}\right)\le\frac{x}{18}\le\frac{7}{3}\times\left(\frac{1}{2}-\frac{1}{6}\right)\)
\(1,5+1\frac{1}{4}\times x=\frac{2}{3}\)
Tìm x:\(\left(2,7.x-1\frac{1}{2}.x\right)\div\frac{2}{7}=\frac{-21}{4}\)
\(3\frac{1}{3}\times x+16\frac{3}{4}=-13,25\)
\(\left(4,5-2\times x\right)\div\frac{3}{4}=1\frac{1}{3}\)
tìm x:
\(\left|x\right|-5\frac{3}{7}\times\left|x\right|-\frac{3}{4}=2\times\left|x\right|+\frac{-15}{2}\)
\(50\%+\frac{2}{3}x=x+4\)
\(0,5x-\frac{2}{3}\left(x+1\right)=\frac{-1}{12}\)
\(\frac{1}{2}\left(x-\frac{2}{3}\right)-\frac{2}{5}\left(2-x\right)=\frac{1}{9}\)
