[Trương Gia Hưng]

2 phần 5 nhân x= 3 phần 5 + 1 phần 2

Answer 1

[Sahara]

\(\dfrac{2}{5}\times x=\dfrac{3}{5}+\dfrac{1}{2}\)
\(\dfrac{2}{5}\times x=\dfrac{6}{10}+\dfrac{5}{10}\)
\(\dfrac{2}{5}\times x=\dfrac{11}{10}\)
\(x=\dfrac{11}{10}:\dfrac{2}{5}\)
\(x=\dfrac{11}{10}:\dfrac{5}{2}\)
\(x=\dfrac{11}{4}\)
