Question

14/x-8/y=18 ;
7/x+5/y=45​

Answer 1

Answer:

x=4xy

y= 13xy/7

Step-by-step explanation:

14/x - 8/y = 18

(14y- 8x)/xy = 18

14y- 8x = 18xy

7y- 4x = 9xy

7/x + 5/y = 45

(7y + 5x)/xy = 45

7y + 5x = 45xy

(7y-4x = 9xy) - (7y+ 5x = 45xy)

-9x = -36xy

x= 4xy

7y - 4x = 9xy

7y- 4xy = 9xy

7y = 13xy

y = 13xy/7
