Question

y x 2 + y / (1/3) =20
Tìm y. Giúp mik với mn ơi!


 

Answer 1

y \(\times\) 2 +\(\dfrac{y}{\dfrac{1}{3}}\) = 20

\(y\times2+y\div\dfrac{1}{3}=20\)

\(y\times2+y\times3=20\)

\(y\times\left(2+3\right)=20\)

\(y\times5=20\)

\(y=20\div5\)

\(y=4\)

Answer 2

y $\times$ 2 +�1331​y​ = 20

�×2+�÷13=20y×2+y÷31​=20

$y\times 2+y\times 3=20$

$y\times \left(2+3\right)=20$

$y\times 5=20$

$y=20÷5$

$y=4$
