<u>Answer:</u>
D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11
<u>Step-by-step explanation:</u>
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.
