\(g,\dfrac{11}{8}+\dfrac{13}{6}=\dfrac{85}{x}\\ \Rightarrow\dfrac{85}{24}=\dfrac{85}{x}\\ \Leftrightarrow x=24\\ k,-\dfrac{7}{x}+\dfrac{8}{15}=-\dfrac{1}{20}\\ \Rightarrow-\dfrac{7}{x}=-\dfrac{7}{12}\\ \Leftrightarrow x=12\)
\(m,\dfrac{x+\left(-2\right)}{5}=\dfrac{-12}{15}\\ \Leftrightarrow15\left(x+\left(-2\right)\right)=5\cdot\left(-12\right)\\ \Leftrightarrow x=-2\\ n,\dfrac{x-1}{-5}=\dfrac{12}{20}\\ \Leftrightarrow20\left(x-1\right)=\left(-5\right)\cdot12\\ \Leftrightarrow x=-2\)
\(p,\dfrac{7}{12}+\dfrac{x}{15}=\dfrac{1}{20}\\ \Rightarrow\dfrac{x}{15}=-\dfrac{8}{15}\\ \Leftrightarrow x=-8\)
Đúng 5
