Question

x+y=4, x+y=5
Find the solution of equation

Answer 1

Answer:

Step-by-step explanation:

Given that  x∗y=4  

So  y=4/x  

And x+y=5  

Or substituting the value of  y  in the above equitation

x+4/x=5  

x2−5x+4=0  

Solving the equation  x=1,4  

So  y=4,1  

Hence x−y would be 1–4=-3, 4–1=3

Answer

x−y=(−3,3)
