Question

Tìm y

y x \(\dfrac{3}{5}\) + y x \(\dfrac{1}{2}\) = \(\dfrac{11}{15}\)

Answer 1

`y xx3/5+y xx1/2=11/15`

`y xx(3/5+1/2)=11/15`

`y xx(6/10+5/10)=11/15`

`y xx11/10=11/15`

`y=11/15:11/10`

`y=11/15xx10/11=2/3`

Answer 2

`y xx 3/5 + y xx 1/2 = 11/15`

`=> yxx(3/5 + 1/2) = 11/15`

`=> y = 11/15 : ( 6/10 + 5/10)`

`y=11/15 : 11/10 `

` y = 11/15 xx 10/11 = 10/15 = 2/3`

Answer 3

=>11/10y=11/15

=>y=2/3

Answer 4

`y xx 3/5 + y xx 1/2 = 11/15`

`=> y xx (3/5 + 1/2) = 11/15`

`=> y xx (6/10 + 5/10) = 11/15`

`=> y xx 11/10 = 11/15`

`=> y               = 11/15 : 11/10`

`=> y              = 11/15 xx 11/10`

`=> y              = 2/3`
