Which system is equivalent to {3x^2 - 4y^2 = 25 {-6x^2 - 2y^2 = 11 a) 3x^2 - 4y^2 = 25 12x^2 + 4y^2 = 22 b) 3x^2 - 4y^2 = 25 -12x^2 + 4y^2 = 22 c) 6x^2 - 8y^2 = 25 -6x^2 - 2y^2 = 11 d) 6x^2 - 8y^2 = 50 -6x^2 - 2y^2 = 11

D) 6x^2 - 8y^2 = 50

-6x^2 - 2y^2 = 11

Step-by-step explanation:

We are given the following two expressions:

and

Now if we look at the option D) and , we can observe that the earlier part in the given expression is just a simplification of 6x^2 - 8y^2 = 50.

and the later part is already the same.

Therefore, the correct answer option is D)  6x^2 - 8y^2 = 50

-6x^2 - 2y^2 = 11.
