Question

2(3u -v )= 5uv ,2 ( u+ 3v ) = 5uv​

Answer 1

Step-by-step explanation:

thanks (3u—v)=5uv

dividing by uv

= (b/v)—(2/u)=5

let 1/v=xand 1/u=y

= 6x—2y=5

= 18x—6y=5

simply (2/v)+(6/v)=5

=2x+6y=5. (2)

adding (1) and (2) we get

20x=20

= x= 1

so y =(5—2) /6 =1/2

x. =1 so 1/v. =1

= v=1

and y=1/2 =1/v

= v= 2
