If 4x + 6y = 3xy and 8x + 9y = 5xy then
We have,
4x + 6y = 3xy …(i)
8x + 9y = 5xy …(ii)
Now, dividing (i) and (ii) by xy we get:
…(iii)
Also, …(iv)
Now, multiplying (iii) by2 and then subtracting it from (iv) we get:
∴ x = 3
Now, substituting the value of x in (iii) we get:
∴ y = 4
Hence, option C is correct
