Answer 2

Step-by-step explanation:

Let 1/x+1= u. and 1/y-1=v

so equations become

5u-2v=1. = 10u-4v =1. ...(1)

2

10u+2v= 5. = 20u+4v=5....(2)

2

From eq(1) u= 1+4v. , put it in eq (2)

10

2× 1+4v. +4v = 5

10

1+4v. +4v =5

5

1+4v+20v. = 5

5

1+24v = 25

24v= 25-1.

24v= 24

v=1

put this in eq (1)

10u-4(1)=1

u=1+5

10

u=6/10

now we know 1/x+1=u

= 1. =6

x+1. 10

6x+6=10

6x= 4

x= 4/6

we also know 1/y-1= v

= 1. = 1

y-1

y-1=1

y= 2
