Question

21/x+47/y=110, 47/x+21/y=162 , x,y not equal 0​

Answer 1

Answer:

x=1/3 and y=1

Step-by-step explanation:

let 1/x=a

1/y=b

21a+47b=110 -------1

47a+21b=162 -------2

adding both equation

68a+68b=272

a+b=4 --------3

subtracting equation 2 from 1

26a-26b=52

a-b=2 -----------4

adding equation 3 and 4

2a=6

a=3

substituting value of a in equation 3

3+b=4

b=4-3=1

a=1/x

3=1/x

x=1/3

b=1/y

1=1/y

y=1

x=1/3

y=1
