Answer 1

Answer:

Let 1/(2x+y) = a & 1/(2x-y) = b

putting in both we get,

a/2 + 12b/7 = 1/2

7a+24b = 7 ----------(1)

7a+4b = 2 ---------(2)

subtracting (2) from (1) we get,

20b = 5

b = 1/4

putting in any now we get ,

a = 1/7

so, we get,

1/(2x+y) = a = 1/7

2x+y = 7 --------(3)

1/(2x-y) = 1/4

2x-y = 4 -------------(4)

adding (3) and (4) now ,

4x = 11

X = 11/4 and Y = 3/2 (Ans)
