3x+y=9 ....(1)
3x-5y=15. ......(2)
-[3x-5y=15]
=> 3x+ y = 9
-3x+5y=-15
..........................
0 +6y=-6
so,y=-1
3x+(-1)=9
3x=10
x=10/3

I am not for sure that what im about to type is the right answer but if im not wrong the amswer is 1over4
Answer:
3(u^2 +u-3)
-------------------
u(u-3)^2
Step-by-step explanation:
u 1
---- + -------
u-3 u
-------------------------
u-3
----------
3
Get a common denominator for the numerator
u *u 1(u-3)
---- + -------
(u-3)u u(u-3)
-------------------------
u-3
----------
3
u *u + (u-3)
-----------
(u-3)u
-------------------------
u-3
----------
3
Now use copy dot flip
u *u + (u-3) 3
----------------- * -------------
(u-3)u u-3
3(u^2 +u-3)
-------------------
u(u-3)^2
7x + 2y = 2
2x - y = 10
2y = - 7x + 2
- y = - 2x + 10
2y = -7x + 2
y = 2x - 10

y= 2x - 10
y = -3.5x + 1
y = 2x - 10
Now, let's find "x" first by doing a substituion !
2x - 10 = - 3.5x + 1
y = 2x - 10
2x + 3.5x = 1 + 10
y = 2x - 10
5.5x = 11
y= 2x - 10

y= 2*2 - 10 = 4 - 10 = -6
In short, the answer would be : y = -6 (Option B).Hope this helps !
