Question

[Nguyễn Thị Minh Thu]

Tìm y, biết:

y \(x\) \(\dfrac{13}{2}\) + 4 = \(\dfrac{11}{2}\)

Answer 1

[Hquynh]

\(y\times\dfrac{13}{2}+4=\dfrac{11}{2}\\ \Rightarrow y\times\dfrac{13}{2}=\dfrac{11}{2}-4\\ \Rightarrow y\times\dfrac{13}{2}=\dfrac{11-4\times2}{2}\\ \Rightarrow y\times\dfrac{13}{2}=\dfrac{3}{2}\\ \Rightarrow y=\dfrac{3}{2}:\dfrac{13}{2}=\dfrac{3}{2}\times\dfrac{2}{13}=\dfrac{3}{13}\)
