Question

1/x+1/y=8;4/x-2/y=2​

Answer 1

Answer:

1/x + 1/y = 8;; 4/x – 2/y = 2

Answer 2

Answer:

X = 0, y = 0

Step-by-step explanation:

1/x + 1/y = 8

Y+x / xy = 8

Y + x = 8xy

X + y = 8xy ----- (1)

4x - 2y = 2

4y -2x / xy = 2

4y - 2x = 2xy

2(2y - x) = 2xy

-x + 2y = 2xy / 2

-x + 2y = xy -------(2)

By using substitution method

X = (8xy - y) -------(3)

-(8xy - y) + 2y = xy

-8xy + y + 2y = xy

3y = xy + 8xy

3y = 9xy

0 = 9xy / 3y

0 = 3x

X = 0

x = 8xy - y

0 = y

Y = 0
