Question 6678
Multiplying equation by-
2x-5y=1....[*3]
-3x+7y=-3..[*2]
<P>Adding both equations after multiplication,we get-
 6x - 15y = 3
-6x + 14y =-6
-------------
     y  =  -3
-------------
<P>
y=-3
Substituting this value in [1] we get,
2x-5y=1
2x-5(-3)=1
2x+15=1
2x=-14
x=-7
<P>
<b>x=-7,y=-3</b>
