( 3x - \(\dfrac{1}{2}\))2 = \(\dfrac{4}{9}\)
=> 3x - \(\dfrac{1}{2}\)= \(\dfrac{4}{9}\): 2
=> 3x - \(\dfrac{1}{2}\)= \(\dfrac{2}{9}\)
=> 3x = \(\dfrac{2}{9}\)+ \(\dfrac{1}{2}\)
=> 3x= \(\dfrac{13}{18}\)
=> x = \(\dfrac{13}{54}\)
Chúc bạn học tốt !
\(\left(3x-\dfrac{1}{2}\right).2=\dfrac{4}{9}\)
\(\Rightarrow\left(3x-\dfrac{1}{2}\right)=\dfrac{4}{9}:2\)
\(\Rightarrow\left(3x-\dfrac{1}{2}\right)=\dfrac{2}{9}\)
\(\Rightarrow3x=\dfrac{2}{9}+\dfrac{1}{2}\)
\(\Rightarrow3x=\dfrac{13}{18}\)
\(\Rightarrow x=\dfrac{13}{18}:3\)
\(\Rightarrow x=\dfrac{13}{54}\)
Chúc bạn học tốt!
bn ơi nếu muốn hỏi mấy bài thường thì sang OLM nhé
\(\left(3x-\dfrac{1}{2}\right)2=\dfrac{4}{9}\)
\(3x-\dfrac{1}{2}=\dfrac{4}{9}:2=\dfrac{4}{18}\)
\(\Rightarrow3x=\dfrac{4}{18}+\dfrac{1}{2}=\dfrac{13}{18}\)
\(\Rightarrow x=\dfrac{13}{18}:3=\dfrac{13}{54}\)
