2x+2y=6

5x+2y =4

Multiply eq 1 by 5 and equation 2 by -2

10x+10y = 30

-10x - 4y = -8

Now adding we get

6y = 22

Divide by 2

3Y =11

<h3>Answer: Choice C</h3>

Here's how the verification would look like

$\frac{\sin^2x+\cos^2x}{\cos x} = \sec x$

$\frac{1}{\cos x} = \sec x$ using the identity here

$\sec x = \sec x$
