Question

[thai thi bai]

x/2+3/4=6/7 ai bik chir vs :(

Answer 1

[Lê Minh Vũ]

\(\dfrac{x}{2}+\dfrac{3}{4}=\dfrac{6}{7}\)

\(\dfrac{x}{2}=\dfrac{6}{7}-\dfrac{3}{4}\)

\(\dfrac{x}{2}=\dfrac{3}{28}\)

\(x\times28=3\times2\)

\(x\times28=6\)

\(x=\dfrac{3}{14}\)

Answer 2

[Thiên An]

\(\dfrac{x}{2}+\dfrac{3}{4}=\dfrac{6}{7}\)

\(\Leftrightarrow\dfrac{x}{2}=\dfrac{6}{7}-\dfrac{3}{4}\)

\(\Leftrightarrow\dfrac{x}{2}=\dfrac{3}{28}\)

\(\Rightarrow x=\dfrac{3}{14}\)
