Question

yx1/3+yx2/5=11/15

Answer 1

\(y=\dfrac{11}{25}:\left(\dfrac{1}{3}+\dfrac{2}{5}\right)=\dfrac{11}{25}:\dfrac{11}{15}=\dfrac{15}{25}=\dfrac{3}{5}\)

Answer 2

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

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

`y xx 11/15 = 11/15`

     `y          = 11/15 : 11/15`

      `y        = 1`

Answer 3

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

\(y\times\left(\dfrac{1}{3}+\dfrac{2}{5}\right)=\dfrac{11}{15}\)

\(y\times\dfrac{11}{15}=\dfrac{11}{15}\)

\(y=\dfrac{11}{15}:\dfrac{11}{15}\)

\(y=\dfrac{11}{15}\times\dfrac{15}{11}\)

\(y=1\)

Answer 4

y=1

Answer 5

y=1

Answer 6

y=1

Answer 7

yx1/3+yx2/5=11/15

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

y  x   7/15     = 11/15

y                   = 11/15 :7/15

y                   = 11/7

Answer 8

y = 1

Answer 9

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

=> y x 11/15 = 11/15

=> y = 1

Answer 10

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

\(y\times\left(\dfrac{1}{3}+\dfrac{2}{5}\right)=\dfrac{11}{15}\)

\(y\times\dfrac{11}{15}=\dfrac{11}{15}\)

\(y=1\)

Answer 11

y = 1 vì :

1 x 1/3 + y x 2/5 = 11/15

1/3 + 2/5 = 11/15
