Explore the solution space of an equation? Lets say I have a equation:
$x = \frac{A}{B} \times k$
and I want to know all values that satisfy the constraint where $x = 1$, and the limits of $A$, $B$ and $k$ are$-10$ to $10$. How would I go about doing this?
Note: the variables are real numbers

Suppose $A,k$ were anything. Could you choose $B$ to satisfy $x=1$? When is there no such $B$?
