You have one equation and two unknowns (x & y).

Unless some other relationship or constraint is given - you cannot calculate values of both the variables explicitly.

Every ordered pair \(\displaystyle \left ( x,\frac{849492.66}{x} \right )\) is a solution to this equation. Imposing conditions on \(\displaystyle x\) and \(\displaystyle y\) restricts the set of solutions.

Except when x = 0

Since no operation between the variables 'x' and 'y' has been defined - we can assume it to be concatenation (which again has infinite # of solutions)

one solution could be;

x = 849

y = 492.66
