Question

plz plz solve this anyone plz it's urgent!!!!!!!​

Answer 1

Answer:

a = -2.5

Step-by-step explanation:

let 1/x =p  & 1/y=q

2/x  +2/3y =1/6

2p+2q/3 =1/6

6p+2q=1/2.....(1)

3/x +2/y =0

3p+2q = 0....(2)

multiply eq(2) from 2

6p +4q =0 ....(3)

subtract eq (1) from(3):

2q= -1/2

q= -1/4  

1/x = -1/4

x=-4

putting value of q in (2)eq

3p -1/2 = 0

p= 1/6

1/y =1/6

y=6

y=ax-4

6 = a*-4  -4

10 = -4a

-2.5 =a
