A) 1,2
B) 0, 0
C) \[-1,\text{ }2\]
D) \[1,-2\]
Correct Answer: A
Solution :
We have, \[\frac{2x+5y}{xy}=6\] or \[\frac{2}{y}+\frac{5}{x}=6\] ?.(1) Also, \[\frac{4x-5y}{xy}=-3\] or \[\frac{4}{y}-\frac{5}{x}=-3\] ....(2) Let \[\frac{1}{y}=a\] and \[\frac{1}{x}=b\] So, (1) and (2) become \[2a+5b=6\] ...(3) and, \[4a-5b=-3\] ...(4) Adding (3) and (4), we get \[a=\frac{1}{2}\] and \[b=1\] [From (3)] \[\therefore \] \[x=1\] and \[y=2\]You need to login to perform this action.
