Answer:
(x, y) = (4, 9)
Step-by-step explanation:
Perhaps the ordered pair you want is the one that satisfies both equations.
We can find that by equating the expressions for y:
x +5 = 3x -3
8 = 2x . . . . . . . . add 3-x to both sides
4 = x . . . . . . . . . divide by 2
y = 4+5 = 9
The ordered pair is (x, y) = (4, 9).

<h3>Answer:</h3>
sec²(x)
<h3>Explanation:</h3>
As required:
... = (sin²(x)/cos²(x))(1 +(cos²(x)/sin²(x))
... = (sin²(x)·(sin²(x)+cos²(x)) / (cos²(x)·sin²(x))
... = 1/cos²(x) = sec²(x)
_____
Alternatively, multiply out the given expression, then use trig identities.
... = tan²(x) + (tan(x)·cot(x))² = tan²(x) +1 = sec²(x)
