\(\dfrac{2-x}{4}=\dfrac{3x-1}{-3}\\ \Rightarrow-3\left(2-x\right)=4\left(3x-1\right)\\ \Rightarrow3x-6=12x-4\\ \Rightarrow12x-4-3x+6=0\\ \Rightarrow9x+2=0\\ \Rightarrow9x=-2\\ \Rightarrow x=-\dfrac{2}{9}\)
\(\dfrac{2-x}{4}=\dfrac{3x-1}{-3}\)
⇒\(\dfrac{3.\left(2-x\right)}{12}\)=\(\dfrac{4.\left(3x-1\right)}{12}\)
⇒\(6x-3=12x-4\)
⇒1=6x
⇒x=\(\dfrac{1}{6}\)
Chúc bạn học tốt!
\(\dfrac{2-x}{4}=\dfrac{3x-1}{-3}\)
\(\Rightarrow-3\left(2-x\right)=4\left(3x-1\right)\)
\(-6+3x=12x-4\)
\(3x-12x=6-2\)
\(-9x=4\)
\(x=\dfrac{4}{-9}\)
