Giai phuong trinh:
a)\(\frac{4+9x}{9x^21}=\frac{3}{3x+1}-\frac{2}{1-3x}\)
b)\(\frac{2x-3}{x+1}+\frac{x^2-5x+10}{\left(x+1\right)\left(x-3\right)}=\frac{3x-5}{x-3}\)
c)\(\frac{x\left(x+4\right)}{2x-3}=\frac{x^2+4}{2x-3}+1-\frac{2}{3-2x}\)
d)\(\frac{1}{x+2}+\frac{x}{x-3}=1-\frac{5x}{\left(x+2\right)\left(3-x\right)}-\frac{1}{x+2}\)
Giải bài tập :
a) \(\frac{3x+2}{2}\) - \(\frac{3x+1}{6}\) = \(\frac{5}{3}\) + 2x
b) \(\frac{x+4}{5}\) - x + 4 = \(\frac{x}{3}\) - \(\frac{x-2}{2}\)
c) \(\frac{4x+3}{5}\) - \(\frac{6x-2}{7}\) = \(\frac{5x+4}{3}\) + 3
d) \(\frac{5x+2}{6}\) - \(\frac{8x-1}{3}\) = \(\frac{4x-2}{5}\) - 5
e) \(\frac{2x-1}{5}\) - \(\frac{x-2}{7}\) = \(\frac{x+7}{15}\)
f) \(\frac{1}{4}\)(x + 3) = 3 - \(\frac{1}{2}\)(x + 1) - \(\frac{1}{3}\)(x - 2)
Các cậu ơi, ai giải được thì giải giúp tớ với. Tớ đang cần rất gấp ạ, tớ cảm ơn các cậu trước nha ^^.
Giải các phương trình sau:
a/ \(\frac{4x-3}{x-5}=\frac{29}{3}\)
b/ \(\frac{4x-5}{x-1}=2+\frac{x}{x-1}\)
c/ \(\frac{2x+5}{2x}-\frac{x}{x+5}=0\)
d/ \(\frac{2x-1}{5-3x}=2\)
e/ \(\frac{7}{x+2}=\frac{3}{x-5}\)
f/ \(\frac{12x+1}{11x-4}+\frac{10x-4}{9}=\frac{20x+17}{18}\)
\(1.\frac{1}{x^2-2x+2}+\frac{2}{x^2-2x+3}=\frac{6}{x^2-2x+4}
\)
2.\(\frac{2x^4}{\left(x+1\right)^2}-\frac{5x^2}{x+1}+2=0\)
3.\(\left(x+\frac{1}{x}\right)^2-6\left(x+\frac{1}{x}\right)+8=0\)
4.\(\left(x^2+\frac{1}{x^2}\right)-4\left(x+\frac{1}{x}\right)+6=0\)
5.\(\frac{2x}{3x^2-x+2}-\frac{7x}{3x^2+5x+2}=1\)
Giải phương trình:
\(\frac{1}{x^2-3x+2}+\frac{1}{x^2-5x+6}-\frac{3}{x^2-4x+3}=0\)
