Answer:
21/X+47/Y=110.....1
47/X+21/Y=162....2
LET 1/X=A,1/Y=B
FROM 1 AND 2
21A+47B=110....3
47B+21A=162...4
ADDING 3 AND 4
21A+47B+47A+21B= 110+162
68A+68B=272
DIVIDING BY 68
A+B=4....5
SUBTRACTING 3 FROM 4
47A-21A+21B-47B=162-110
26A-26B=52
DIVIDING BY 26
A-B=2......6
ADDING 5 AND 6
A+A+B-B=4+2
2A=6
A=3
SUBSTITUTING A=3 IN EQUATION 5
A+B=4
3+B=4
B=1
RESUBSTITUTING THE VALUES OF A AND B
A=1/X. ,B=1/Y
X=1/A. ,Y=1/B
X=1/3. ,Y=1/1= 1
IT'S THE SOLUTION
