Answer:
x=(k+3)/y
Step-by-step explanation
First, we simplify by adding 3 to both sides of the equation
xy-3+3=k+3
Now it's xy=k+3
To get x we divide both sides by y
So x=(k+3)/y
5.8/1.2 = 58/12 = 4.83333333
rounded to the nearest hundredth
4.83
There are infinitely many solutions.
Algebraically, we can eliminate
and try to solve for
:

Then



which is the equation of an ellipse.
