Question

Tìm y: y × 3,6 + 7,4 × y - y = 32,48

Answer 1

` y × 3,6 + 7,4 × y - y = 32,48`

`=> y × 3,6 + 7,4 × y - y xx1= 32,48`

`=> y xx ( 3,6 + 7,4 -1)=32,48`

`=> y xx 10=32,48`

`=>y =32,48 : 10`

`=> y= 3,248`

Vậy `y=3,248`

Answer 2

y x 3,6 + 7,4 x y - y = 32,48

⇒y x 3,6 + 7,4 x y - 1 x y = 32,48

⇒y x (3,6+7,4-1)=32,48

⇒y x 10 = 32,48

⇒y = 32,48 : 10

⇒y =3,248

Vậy y = 3,248

Answer 3

\(y\times3,6+7,4\times y-y=32,48\\ y\times\left(3,6+7,4-1\right)=32,48\\ y\times10=32,48\\ y=32,48:10\\ y=3,248\)
