Question

2/x + 1/y =13 , 5/x - 4/ y = -2 ( where =/ 0, Y =/ 0)

Answer 1

Answer:

Step-by-step explanation:

(2/x) + (1/y)=13

(5/x) - (4/y)=-2

now let (1/x)=p and (1/y)=q

so, 2p + q =13 .... (i)

and 5p - 4q=-2.....(ii)

(ii)+(i) ×4

8p+4q=52

+5p-4q=-2

13p=50

so, p=50/13

therefore q=69/13......{5×(50/13) - 4q = -2}

since 1/x=p

        so x=13/50

since 1/y=q

         so y=13/69

Hope its clear.! ^_^
