tìm x, y biết \(\frac{\left(2x+1\right)}{5}\)=\(\frac{\left(4y-5\right)}{9}\)=\(\frac{2x+4y-4}{7x}\)
tìm x , biết
1, 2\(\left(\frac{3}{4}-5x\right)=\frac{4}{5}-3x\)
2, \(\frac{3}{2}-4\left(\frac{1}{4}-x\right)=\frac{2}{3}-7x\)
3, 3\(\left(\frac{1}{2}-x\right)+\frac{1}{3}=\frac{7}{6}-x\)
4, a\(\left(\frac{1}{2}-x\right)-5\left(x-\frac{3}{10}\right)=\frac{7}{4}\)
\(4\left(\frac{1}{2}-x\right)-5\left(x-\frac{3}{10}\right)=\frac{7}{4}\)
\(2\left(\frac{3}{2}-x\right)-\frac{1}{3}=7x-\frac{1}{4}\)
\(-\frac{3}{2}\left(5-\frac{1}{6}\right)+4\left(x-\frac{1}{2}\right)=1\)
Tìm x, biết
