Answer:
The answere is (9,3)
Step-by-step explanation:
first equation
x - 2y = 3
9 - 2(3) = 3
9-6 = 3
3 = 3
second equations
2x - 3y = 9
2(9) - 3(3) = 9
18 - 9 =9
9 = 9
or
x - 2y = 3
x = 2y + 3
2(2y + 3 ) - 3y = 9
4y +6 - 3y = 9
y + 6 = 9
y =3
x - 2(3) = 3
x - 6 =3
x = 9
so (9,3)

Answer:
I believe your answer is correct.
Step-by-step explanation:
Answer:
The answer is cosx cot²x ⇒ the first answer
Step-by-step explanation:
∵ cot²x = cos²x/sin²x
∵ secx = 1/cosx
∴ cot²x secx - cosx = (cos²x/sin²x)(1/cosx) - cosx
= (cosx/sin²x) - cosx
Take cosx as a common factor
∴ cosx[(1/sin²x) - 1] ⇒ use L.C.M
∴ cosx[1-sin²x/sin²x]
∵ 1 - sin²x = cos²x
∴ cosx(cos²x/sin²x) = cosx cot²x
185 * 17 = 3145 so that means 3145 / 17 = 185
