Hii Mate !!

Here is your answer !!

Question : 7y - 4 / 2y + 11 = 9 / 5.

Solution :

7y - 4 / 2y + 11 = 9 / 5

By Cross Multiplication method , we get

5 ( 7y - 4 ) = 9 ( 2y + 11 )

35y - 20 = 18y + 99

35y - 18y = 99 + 20

17y = 119

y = 119 / 17

y = 7.

Hence,

therefore the value of y is equal to 7.

Hope it helps you β™₯
