Giai bptr sau
\(\dfrac{6x+5}{4}-\dfrac{x-3}{2}< \dfrac{6x-1}{3}+\dfrac{7x-1}{12}\)
Giải PT sau?:
\(\dfrac{7x-1}{6}+2x=\dfrac{16-x}{5}\)
Gỉai bptr sau:
a,\(\dfrac{x-5}{4}-\dfrac{2x-1}{2}< 3\)
b,\(\dfrac{5x^2-3}{5}+\dfrac{3x-1}{4}>\dfrac{x\left(2x+3\right)}{2}-5\)
\(\dfrac{7x-1}{6}+2x=\dfrac{16-x}{5}\)

a/2x(3x-1)=6x^2-13
b/\(\dfrac{x}{3}-\dfrac{2x+1}{6}=\dfrac{x}{6}-x\)
Giups mk vs ạ ai nhanh mk tick nha ><
Giải các phương trình sau:
\(e.\dfrac{12}{1-9x^2}=\dfrac{1-3x}{1+3x}-\dfrac{1+3x}{1-3x}\)
\(f.\dfrac{6x+1}{x^2-7x+10}+\dfrac{5}{x-2}=\dfrac{3}{x-5}\)
\(g.\dfrac{2}{x+2}-\dfrac{2x^2+16}{x^3+8}=\dfrac{5}{x^2-2x+4}\)
\(h.\dfrac{8}{x-8}+\dfrac{11}{x-11}=\dfrac{9}{x-9}+\dfrac{10}{x-10}\)
Giải phương trình sau
\(\dfrac{5\left(x-1\right)+2}{6}-\dfrac{7x-1}{4}=\dfrac{2\left(2x+1\right)}{7}-5\)
