Answer 1

[Sahara]

\(\dfrac{1}{5}\times y+0,4\times y+y=32\)
\(\left(\dfrac{1}{5}+0,4+1\right)\times y=32\)
\(\dfrac{8}{5}\times y=32\)
\(y=32:\dfrac{8}{5}\)
\(y=20\)

Answer 2

[tú phạm]

1/5  * y + 0,4 * y + y = 32

1/5 * y *0,4 * y + y * 1 = 32
( 1/5 + 0,4 + 1 ) * y = 32
8/5 * y = 32
y = 32 : 8/5
y = 20
