Question

solve for x and y
3x+2y/xy=1;4x-2y/xy=13.​

Answer 1

hope it's helpful to uhhh......

mark me brainliest if u like the solution.....!!!!

Answer 2

Answer:

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.
