Question

Tìm x:

X/2-1/3=2/5

Answer 1

\(\frac{x}{2}-\frac{1}{3}=\frac{2}{5}\)

\(\Rightarrow\frac{x}{2}=\frac{2}{5}+\frac{1}{3}\)

\(\Leftrightarrow\frac{x}{2}=\frac{11}{15}\)

\(\Rightarrow15x=11\)x\(2\)

\(\Leftrightarrow15x=22\)

\(\Rightarrow x=22:15\)

\(\Leftrightarrow x=\frac{22}{15}\)

Chúc bạn học giỏi nha!!!
