\(=\frac{4x}{6}+\frac{2x-1}{6}\)
\(=\frac{6x-1}{6}\)
\(=\frac{6x}{6}-\frac{1}{6}=x-\frac{1}{6}\)
Cho mình xin lỗi đề là gì nè : \(\frac{2x}{3}+\frac{2x-1}{6}\)
Rút gọn
a)\(\frac{3}{2x+6}-\frac{x-6}{2x^2+6x}\)
b)\(\left\{\frac{2x+1}{2x-1}-\frac{2x-1}{2x+1}\right\}:\frac{4x}{10x-5}\)
c)\(\frac{x^2+x}{5x^2-10x+5}:\frac{3x+3}{5x-5}\)
Giải phương trình sau :
a) \(\frac{x^2-2x+1}{x^2-2x+2}+\frac{x^2-2x+2}{x^2-2x+3}=\frac{7}{6}\)
b) \(\frac{x+2}{2008}+\frac{x+3}{2007}+\frac{x+4}{2006}+\frac{x+2028}{6}=0\)
Giai phương trình : a ) \(\frac{2x}{3}+\frac{2x-1}{6}=4-\frac{x}{3}\)
Giair phương trình nha :
a ) \(\frac{2x}{3}+\frac{2x-1}{6}=4-\frac{x}{3}\)
Giải phương trình
a) \(\frac{2x-5}{x+5}=3\)
b) \(\frac{x^2-6}{x}=x+\frac{3}{2}\)
c)\(\frac{\left(x^2
+2x\right)-\left(3x+6\right)}{x-3}=0\)
d)\(\frac{5}{3x+2}=2x-1\)
e)\(\frac{2x-1}{x-1}+1=\frac{1}{x-1}\)
g)\(\frac{x+3}{x+1}+\frac{x-2}{x}=2\)
Giải phương trình
a) \(\frac{2}{x+\frac{1}{1+\frac{x+1}{x-2}}}=\frac{6}{3x-1}\)
b) \(\frac{3x-1}{x-1}-\frac{2x+2}{x+2}+\frac{4}{x^2+2x-3}=1\)
Giải phương trình
a) \(\frac{2x-5}{x+5}=3\)
b) \(\frac{x^2-6}{x}=x+\frac{3}{2}\)
c) \(\frac{\left(x^2+2x\right)-\left(3x+6\right)}{x-3}=0\)
d) \(\frac{5}{3x+2}=2x-1\)
e) \(\frac{2x-1}{x-1}+1=\frac{1}{x-1}\)
g) \(\frac{x+3}{x+1}+\frac{x-2}{x}=2\)
Làm ơn. Help me!!
giúp mình với
làm phép tính
c) \(\frac{1}{3x-2}-\frac{4}{3x+2}-\frac{3x-6}{4-9x^2}\)
d) x - 2 \(-\frac{x^2-10}{x+2}\)
e)\(\frac{1}{2x-2y}-\frac{1}{2x+2y}+\frac{y}{y^2-x^2}\)
g)\(\frac{4-2x+x^2}{x+2}-2-x\)
i)\(\frac{1}{2x+3}-\frac{1}{2x-3}+\frac{x-2}{2x^2-x-3}\)
\(A=\left(\frac{2x+1}{2x-1}-\frac{2x-1}{2x+1}\right):\frac{8x}{3-6x}\)
a) Rút gọn biểu thức A
b) Tìm x khi A=\(-\frac{3}{4031}\)
