(1)                                \frac{x + y}{xy} = 2        ............(1)

                                               &

                                   \frac{x - y}{xy} = 6         ............(2)

From, eq(1) we find:

x + y = 2(x)(y)

x = 2xy - y.                                                                 ................(3)

From, eq(2) we find:

x - y = 6xy

x = 6xy + y

2xy - y = 6xy + y

- y - y = 6xy - 2xy

- 2y = 4xy

-2 = 4x

x= - 1/2

From, eq(3) we find:

-1/2 = 2(-1/2)y-y

y = 1/2 - y

2y = 1/2

y = 1/4

(2)                  \frac{6}{x + y} = \frac{7}{x - y}        ............(1)

                                               &

                     \frac{1}{2(x + y} = \frac{1}{3(x - y}         ............(2)

From, eq(1) we find:

6/7 = x - y/x + y

x = {6(x + y) + 7y}/7                                                                ................(3)

From, eq(2) we find:

3x - 3y = 2x + 2y

3x - 2x = 2y + 3y

x = 5y

x= 5y.                                                                                       ................(4)

From, eq(3) we find:

5y = 42(6y) + 49y

-44y = 252y

252y + 44y = 0

296y = 0

y = 0.

Then:

x = 5(0)

x=0
