In this question, I tried this:
sin^2(180-x) cosec(270+x) + cos^2(360-x) sec(180-x), where cosec(x) = 1/sin(x) and sec(x) = 1/cos(x)
-sin^2(180-x) = sin^2(x) and cos^2(x) = cos^2(x)
-The sin^2 and the 1/sin(x) cancle out along with the cos^2 and the 1/cos(x)
Therefore, I am left with...
I see where it comes from but problem is I got stuck at 40x = 1600+10y
I couldn't get an equation in terms of x

What I have done:
I changed all fractions to common denom and that gave me
5y-5x=1 (1) *I numbered the fractions
5y+2x=5 (2)
Then: 5y=5-2x
Substitute into equation 1
(5-2x)-5x=1
5-7x=1
x=4/7
Thing is my answer says I should be getting x=0
Any hints?
