Answer: The anser is Either x=5 & y= 1
Or x =1 & y =5.
Step-by-step explanation:
Given that, x+y = 6 & xy= 5
We know, (x-y)²= (x+y)²-4xy = 6²-4×5=16
=> x-y = +-√16
=> x-y=+-4
Let, x-y = +4 & x+y =6
Then adding two above equation we get
2x = 10
=> x = 5. & y = 6-x = 6-5=1
Again, let, x-y = -4 & x+y=6
Second equation subtract from first equation we get,
-2y = - 10 => y = 5 & x = 1.

Answer:
1 and 5 or 5 and 1 are value of x and y.
Step-by-step explanation:
x*y=5 and x+y=6
x = 5/y put in second eq.
5/y + y = 6
5 + y /y,= 6
5 + y = 6y
5 = 5y
1 = y => x = 5
1 and 5 are the answer.
