Question

solve the simultaneous equation 1/x+1/y=8;;4/x-2/y=2​

Answer 1

Answer :

x = 1/3, y = 1/5

Solution :

Given,

1/x + 1/y = 8

Let, 1/x = p and 1/y =q

⟶ p + q = 8

p = 8 - q ------ equation 1

⟶ 4/x - 2/y = 2

4p - 2q = 2

2p - q = 1

Substitute eq 1 in this

2(8 - q) - q = 1

16 -2q - q = 1

3q = 15

q = 5

From equation 1,

p = 8 - 5

p = 3

∴ x = 1/3, y = 1/5
