Question

pls answer above question​

Answer 1

Answer:

5/x + 1/y = 2 and 6/x - 3/y = 1

let 1/x = m and 1/y = n

then above equation will become

5m + n = 2 .....(1). and 6m - 3n = 1 .....(2)

multiply ...(1) by 3 then add both the equations

we get

15m + 3n = 6

6m -3n = 1

→ 21m = 7

m = 1/3

put this in any of the equation

we get

3n = 1

again

n = 1/3

as we assume

m = 1/x = 1/3

so x = 3

and

n = 1/y = 1/3

so y = 3

therefore x = 3 and y = 3

hope this will help you.
