Bài 1: Tính

a, \(\left(5\sqrt{7}+7\sqrt{5}\right):\sqrt{35}\)

b, \(\left(2\sqrt{8}-3\sqrt{3}+1\right):\sqrt{6}\)

\(a,\frac{x-3}{2}+\frac{4x+1}{3}=\frac{2x-7}{6}\)

\(b,\frac{x-4}{5}+\frac{3x-2}{10}-x=\frac{2x-5}{3}-\frac{7x+5}{6}\)

\(c,\frac{2\left(x-3\right)}{4}+\frac{x-5}{3}=\frac{13x+4}{12}\)

Giúp mình với

\(a,\frac{8x-3}{4}-\frac{3x-2}{2}=\frac{2x-1}{2}+\frac{x+3}{4}\)

\(b,\frac{x+3}{2}-\frac{x-1}{3}=\frac{x+5}{6}+1\)

\(c,\frac{2\left(x-3\right)}{7}+\frac{x-5}{3}=\frac{13x+4}{21}\)

Thực hiện phép tính:

1,\(\frac{1-2x}{2x}+\frac{2x}{2x-1}+\frac{1}{2x-4x^2}\)

2,\(\frac{x^2+2}{x^3-1}+\frac{2}{x^2+x+1}+\frac{1}{1-x}\)

3,\(\frac{x}{x-2y}+\frac{x}{x+2y}+\frac{4xy}{4y^2-x^2}\)

4,\(\frac{2x}{x^2+2xy}+\frac{y}{xy-2y^2}+\frac{4}{x^2-4y^2}\)

5,\(\left(\frac{9}{x^3-9x}+\frac{1}{x+3}\right):\left(\frac{x-3}{x^2+3x}-\frac{x}{3x+9}\right)\)
