You can put this solution on YOUR website!
Do you mean what is the solution of this system?
1.xy=3
2.x%2By=-1
From eq. 1,
y=3%2Fx
Then from eq. 2,
x%2By=-1
x%2B3%2Fx=-1
x%5E2%2B3=-x
x%5E2%2Bx%2B3=0
There are no real solutions as you can see by graphing the two functions below (they never intersect).
