Question

Solue the simultaneous equation: 4/x + 5/y =7;3/x + 4/y =11/2
​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer: x= 2 , y=1

Step-by-step explanation:

take 1/x=u, 1/y=v

u will get a equation as 4u+5v=7 and 6u+8v=11

multiply the first equation with 6 and second with 4

u will get 24u+30v=42 and 24u+32v=44

now use elimination method

u will get u=1/2 and v=1

therefore x=2 , y=1
