uri · Answer

Okay,I'll tell you.

anonymous · Answer

i just really neeed an answer

anonymous · Answer

i have 5 mins and 7 other questions

uri · Answer

3x – 2y = 9
3x + 2y = 14
=======
6x=24
x=23/6
x=3.8

-2y+2y will be cancelled. 

No use to solve the whole question because x is 3.8,where as you want x to be 5.

uri · Answer

Well,I don't know the answer.....I just know how to solve.

anonymous · Answer

Put $x=5$ and $y=3$ in each equation and check which equation is satisfying these values.

uri · Answer

@waterineyes she wants only ansurs...

anonymous · Answer

Like I do for option D:

$2x - y = 7$

Put $x=5$ and $y=3$:
$2(5) - 3 = 7$
$7=7$, so one equation is satisfied, check for others. :)

Okay I got you Miss Uri. :)
