\(\frac{2}{x-1}=\frac{-3}{\frac{1}{4}}=-12\)
\(\Leftrightarrow12x-12=2\)
\(\Leftrightarrow12x=2+12=14\Leftrightarrow x=\frac{14}{12}=\frac{7}{6}\)
\(\frac{2}{x-1}=\frac{-3}{\frac{1}{4}}=-12\)
\(\Leftrightarrow12x-12=2\)
\(\Leftrightarrow12x=2+12=14\)
\(\Leftrightarrow x=\frac{7}{6}\)
\(\frac{2}{x-1}=\frac{-3}{\frac{1}{4}}\)
\(\Rightarrow2\cdot\frac{1}{4}=-3\left(x-1\right)\)
\(\Rightarrow\frac{1}{2}=-3x-3\)
đến đây dễ r
\(\frac{2}{x-1}=\frac{3}{\frac{1}{4}}\)
\(\Leftrightarrow\frac{2}{x-1}=12\)
\(\Leftrightarrow x-1=\frac{1}{6}\)
\(\Leftrightarrow x=\frac{1}{6}+1\)
\(\Leftrightarrow\frac{7}{6}\)
\(\frac{2}{x-1}=\frac{-3}{\frac{1}{4}}\)
\(\frac{2}{x-1}=\frac{-12}{1}\)
\(\Rightarrow2.1=\left(x-1\right).\left(-12\right)\)
\(\Rightarrow2=\left(x-1\right).\left(-12\right)\)
\(\Rightarrow\left(x-1\right).\left(-12\right)=2\)
Tự làm tiếp nha . Tìm x
