Question

if x-y/x+y =9. what is the value of x/(-y) ​

Answer 1

Step-by-step explanation:

Given, (x

2

−y

2

)=9 and x−y=1

⇒(x+y)(x−y)=9

⇒(x+y)(1)=9

⇒(x+y)=9

Answer 2

Answer:

x/(-y) = 10/8 = 5/4

Step-by-step explanation:

by cross multiplying,

x-y = 9(x+y)

→ x-y = 9x+9y

→ x-9x = 9y+y

→ -8x = 10y

→ -(x/y) = 10/8 = 5/4

Thus, x/-y = 5/4
