Step-by-step explanation:
1st Step:-
3x+2y/xy=1
=)3x+2y=xy...(i)
2nd Step:-
4x-2y/xy=13
=)4x-2y=13xy...(ii)
ADDING EQUATIONS 1 AND 2,we get,
3x+2y=xy
4x-2y=13xy
---------------
=)7x=14xy
=)1=14xy/7x
=)1=2y
=)y=1/2
Therefore,putting the value of y in 1 we get,
3x+2y=xy
=)3x+2×1/2=x×1/2
=)3x+1=x/2
=)2×(3x+1)=x
=)6x+2=x
=)5x=-2
=)x=-2/5
ANS) x=-2/5
y=1/2
Step-by-step explanation:
First we equate both the equations to find the value of y and then we put the value in either of the equations to find x and y.
Hope this helps........
