Answer 2

Answer:

u = 1 and r =3/2

Step-by-step explanation:

6u/ur + 3r/ur =7ur/ur

= 6/r +3/u =7

3u/ur +9r/ur=11ur/ur

= 3/r +9/u =11

Let 1/r = p and 1/u = q

6p + 3q = 7. eq1

3p + 9q =11. eq2

on multipy by eq 2 by 2 we get 6p + 18q =22

on Eliminating eq 1 and eq 3

we get q =1.

and putting in eq p= 2/3

And putting in eq we get u = 1 and r = 3/2
