Question

Solve 2/x+2y=15 , 2/x-4y=3

Answer 1

Explanation:

2/x+2y-2/x+4y=15-3

2y+4y=12

6y=12

y=2

Put y in 1st eq.

2/x+2(2)=15

2/x+4=15

2/x=15-4

2/x=11

x=2/11

Answer 2

Answer:

(2/x+2y) - (2/x - 4y) = 15 - 3

2/x + 2y - 2/x + 4y = 12

6y = 12

y = 2

Substitute this value of y in any of the above eqn

2/x + 2×2 = 15

2/x = 15 - 4

2/x = 11

x = 2/11
