Question

Solve :
8v -3u = 5uv
6v - 5u = -2uv

Answer 1

3(8v-3u=5uv)
4(6v-5u=-2uv)
so,solving both the equations;
24v-9u=15uv
24v-20u=-8uv
-     +      +
------------------
 0   +11u=23uv
           11=23v
           v=11/23
8v-3u=5uv
8*11/23-3u=5u*11/23
88/23=55u/23+3u
solve the remaining by urself
i had to leave
sorry
(hope it helps u)

Answer 2

Step-by-step explanation:

Divide both sides by uv:

8/u-3/v=5,6/u-5/v= -2

Take 1/u=x and 1/v=y,so the eqn becomes

8x-3y=5.. (i)and 6x-5y= -2.. (ii) then multiplying (i) by 5 and (ii) by 3 we get 40x-15y=25..(iii) and 18x-15y= -6.. (iv) then subtract iv from iii,

12x=31 i. e. X=31/12,

Put x=31/12 in (i) to get

62/3 -3y=5 solve

Y=47/9 then

U=1/x so u=12/31,

V=1/y so v=9/47

hope that it will help u guys
