1) ta có \(\dfrac{2x-2}{5}=3x\Leftrightarrow2x-2=3x.5\Leftrightarrow2x-2=15x\Leftrightarrow13x=-2\Leftrightarrow x=\dfrac{-2}{13}\)
thay \(x=\dfrac{-2}{13}\) và phương trình sau
ta có \(5.\dfrac{-2}{13}+m=4.\dfrac{-2}{13}+\left(1-m\right)\)
\(\Leftrightarrow\dfrac{-10}{13}+m=\dfrac{-8}{13}+1-m\Leftrightarrow2m=\dfrac{-8}{13}+1+\dfrac{10}{13}\)
\(\Leftrightarrow2m=\dfrac{15}{13}\Leftrightarrow m=\dfrac{15}{26}\) vậy \(x=\dfrac{-2}{13};m=\dfrac{15}{26}\)
