Solve this Simultaneous equation..
If you have correct ✔ ans then give the ans. and I mark you as a brainliest...don't give bad ans..if you give I report it...​

Answer 1

Answer:

x = 2 , y = 2

Step-by-step explanation:

1/3x+1/5y=1/15 ; 1/2x+1/3y=1/12

(3x+5y) / 15xy =1/15 ; (2x + 3y) / 6xy = 1/12

15(3x + 5y) = 15xy ; 12(2x + 3y) = 6xy

3x + 5y = xy - (1) ; 4x + 6y = xy - (2)

(1)×4 => 12x + 20y = 4xy

(2)×3 => 12x + 18y = 3xy

( - )

____________

2y = xy

x = 2

subtituting x = 2 in - (1)

3(2) + 5y = 2y

5y - 2y = 6

3y = 6

y = 2
