boi đz · Answer

$\dfrac{3}{5}\times y+y\times\dfrac{2}{5}+y=10$

$y\times\left(\dfrac{3}{5}+\dfrac{2}{5}+1\right)=10$

$y\times\left(\dfrac{3}{5}+\dfrac{2}{5}+\dfrac{5}{5}\right)=10$

$y\times2=10$

$y=10\div2$

$y=5$Câu trả lời: $\dfrac{3}{5}\times y+y\times\dfrac{2}{5}+y=10$

$y\times\left(\dfrac{3}{5}+\dfrac{2}{5}+1\right)=10$

$y\times\left(\dfrac{3}{5}+\dfrac{2}{5}+\dfrac{5}{5}\right)=10$

$y\times2=10$

$y=10\div2$

$y=5$
