Cảm ơn mọi người .  :) 

số nốt còn lại của các nốt có 3 dâylà

88-14-20=54 nốt

số dây đàn được căng trong cây đàn trên là

(14x1)+(20x2)+(54x3)=216 dây đàn

216 nhe

Thanks

Đáp án là 216 dây nha bạn

A là đáp án đúng

Số dây là:(14*1)+(20*2)+[(88-14-20)*3]=216

đáp án là A nha

\(\dfrac{x}{2}-\dfrac{2}{9}=\dfrac{3}{2}-\left(\dfrac{-5}{4}\right)\\ \Rightarrow\dfrac{x}{2}-\dfrac{2}{9}=\dfrac{11}{4}\\ \Rightarrow\dfrac{x}{2}=\dfrac{11}{4}+\dfrac{2}{9}\\ \Rightarrow\dfrac{x}{2}=\dfrac{107}{36}\)

\(\Rightarrow x=\dfrac{107}{36}\times2\\ \Rightarrow x=\dfrac{107}{18}\)
