Question

1/x-1/y=2; 1/x+1/2y=8 solve simultaneous equation​

Answer 1

Step-by-step explanation:

let 1/x = p and 1/y = q

p-q=2. --------(1)

p + q/2 =8 --------(2)

multipling (2) by 2

2p + q = 16 ------(3)

adding (1) and (3)

3p = 18

p= 6 ----(4)

substituting (4) in (2)

6 + q/2 =8

q/2 = 2

q=4

Therefore, x=1/6 and y = 1/4
