The answer is in red but I need someone to show the work PLEASE ?!

(-1, -8)

Step-by-step explanation:

So you would do the simplifying by "subtracting" the equations from each other. So to isolate the x, you could subtract the y away.

   8x + y = -16

  -3x + y = -5

-

11x = -11

x = -1

Then, substitute x into either equation.

8(-1) + y = -16

-8 + y = -16

Isolate y.

y = -8

no

step-by-step explanation:

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
