Question

2 - 4/7 x X = 1/7

Answer 1

\(2-\dfrac{4}{7}\times x=\dfrac{1}{7}\\ \Rightarrow\dfrac{4}{7}\times x=2-\dfrac{1}{7}\\ \Rightarrow\dfrac{4}{7}\times x=\dfrac{13}{7}\\ \Rightarrow x=\dfrac{13}{7}:\dfrac{4}{7}\\ \Rightarrow x=\dfrac{13}{4}\)

Answer 2

\(\dfrac{13}{4}\)

Answer 3

\(\dfrac{4}{7}x=\dfrac{-13}{7}\)

\(x=\dfrac{-13}{4}\)

Answer 4

thấy đề hơi sai sai

Answer 5

2−4/7×x=1/7

⇒4/7×x=2−1/7

⇒4/7×x=13/7

⇒x=13/7:4/7

⇒x=13/4
