We start by identifying the given problem structure: solve the rational equation provided, noting that the answer field indicates two possible ordered pairs of solutions, separated by a comma. The listed candidate solutions to check are -5 and 0, in some order, so the task is to determine which values of x satisfy the equation.

Option A suggests the solution set is -5 and 0 in that particular order: -5, 0. To assess this, one would substitute x = -5 into the original equation, simplifying each rational expression carefully and ensuring both sides match without introducing division by zero. Then substitute x = 0 and repeat the check. If both substitutions satisfy the equation, Option A would be correct for the given order.

Option B suggests the solution set is 0 and -5 in that order: 0, -5. The same substitution process applies, but now you test x = 0 first, then x = -5, verifying whether both values satisfy the equation under this order.

A useful approach when dealing with rational equations is to identify restrictions: values that would make any denominator zero must be excluded from the solution set. Typical denominators in such problems include expressions like (x − 1), (1 − x), (3 − x), or any simplified forms derived during algebraic manipulation. Before checking candidate solutions, confirm that neither -5 nor 0 makes any denominator zero in the original equation. If one of these values makes a denominator zero, it cannot be a valid solution, which would immediately rule out the corresponding option.

If the substitutions show both candidates satisfy the equation (and neither is excluded by a domain restriction), then the solution set would indeed include both values. In that scenario, you would expect the problem to present a pair of solutions, and either ordering given (A or B) could be considered correct depending on how the answer box requires formatting. Conversely, if only one value satisfies the equation, then only the corresponding option containing that value would be correct.

In summary, the method is:
- Check domain restrictions to exclude invalid x values.
- Substitute x = -5 and x = 0 into the original equation, verifying equality on both sides for each.
- Determine which values satisfy the equation and compare with the provided option formats (A: -5,0) vs B: 0,-5.
- If both satisfy, both orders would be acceptable depending on the question’s conventions; if only one satisfies, only the corresponding order is correct.

Note: Without the explicit step-by-step simplification of the given equation in this prompt, the final verdict hinges on direct substitution and domain checks. Proceeding with those checks will confirm which option accurately represents the solution set and whether the two values can appear together in the specified order.
