Question

1716 : y = 12 x 13                                               y x 2/3 + y x 1/6 = 10/3

Answer 1

`1716:y=12xx13`

`1716:y=156`

`y=1716:156`

`y=11`

________________________________-

`y xx 2/3+y xx 1/6=10/3`

`y xx(2/3+1/6)=10/3`

`y xx(4/6+1/6)=10/3`

`y xx5/6=10/3`

`y=10/3:5/6`

`y=10/3xx6/5=4`

Answer 2

1716 : y = 12 \(\times\) 13         

1716 : y = 156

           y = 1716 : 156

           y = 11                                     

\(y\times\dfrac{2}{3}+y\times\dfrac{1}{6}=\dfrac{10}{3}\)

\(y\times\left(\dfrac{2}{3}+\dfrac{1}{6}\right)=\dfrac{10}{3}\)

\(y\times\dfrac{5}{6}=\dfrac{10}{3}\)

\(y=\dfrac{10}{3}:\dfrac{5}{6}\)

\(y=4\)

 

Answer 3

1716 : y = 12 . 13 

⇔ \(\dfrac{1716}{y}\) = 156 

⇔ 1716 = 156.y

⇔ y = 11 

y . \(\dfrac{2}{3}+y.\dfrac{1}{6}=\dfrac{10}{3}\)

⇔ \(\dfrac{5}{6}x=\dfrac{10}{3}\)

⇔ x = 4
