tìm x
\(\frac{4}{5}x^2\left(\frac{x}{3}-\frac{1}{2}\right)-\left(\frac{1}{2}x-\frac{2}{3}\right)\left(\frac{4x^2}{3}+1\right)=\frac{22}{45}x^2\)
Tìm x biết :
a ) \(\left(\frac{2}{3}x-\frac{1}{2}\right)\left(\frac{2}{3}x+\frac{3}{4}\right)< 0\)
b) \(\frac{x+1}{2015}+\frac{x+2}{2014}=\frac{x+3}{2013}+\frac{x+2}{2014}\)
Tìm X: \(\frac{\left(x+1\right)^2-\frac{x}{2}}{4}=\frac{\left(2x-3\right)^2}{3}-\frac{\frac{x+1}{4}-\frac{x\left(3-2x\right)}{3}}{4}\)

Tìm x?
Tìm x:
a) \(\frac{1}{2}x+2\frac{1}{2}=3\frac{1}{2}x-\frac{3}{4}\)
b) \(\frac{2}{3}x-\frac{2}{5}=\frac{1}{2}x-\frac{1}{3}\)
c) \(\frac{1}{3}x+\frac{2}{5}\left(x+1\right)=0\)
Tìm x:
\(a)5x+\frac{1}{2}-x=\frac{2}{3}\)
\(b)\frac{-2}{3}x+\frac{3}{7}+\frac{1}{2}x=\frac{-5}{6}\)
Tìm x :
x + (x + 1 ) + ( x+2 ) + ..+ ( x+2003 ) =2004
\(2\frac{1}{3}+\left(x-\frac{3}{2}\right)=\left(3-\frac{3}{2}\right)x\)
