\(\frac{-2,6}{x}=\frac{-12}{42}\Rightarrow x=-2,6:\frac{-12}{42}=\frac{13}{5}:\frac{2}{7}=\frac{91}{10}=9,1\)
Ta có: \(\frac{-2,6}{x}=\frac{-12}{42}\)
\(\Rightarrow x=42.\left(-2,6\right):\left(-12\right)\)
\(\Rightarrow x=9,1\)
Vậy x = 9,1
\(\frac{-2.6}{x}\)= \(\frac{-12}{42}\)
=> -2,6 .42 = x . (-12)
=> -109,2 = x . (-12)
=> x = -109,2 : (-12 )
=> x = 9.1
