Bài 1: Giải các phương trình
a, 5+\(\frac{96}{x^2-16}\)= \(\frac{2x-1}{x+4}\)- \(\frac{3x-1}{4-x}\)
b, \(\frac{3x+2}{3x-2}\) - \(\frac{6}{2+3x}\)= \(\frac{9x^2}{9x^2-4}\)
c, \(\frac{x+1}{x^2+x+1}\) - \(\frac{x-1}{x^2-x+1}\)= \(\frac{3}{x\left(x^4+x^2+1\right)}\)
d, \(\frac{2x-5}{x-2}\) - \(\frac{3x-5}{x-1}\)= -1
