Question

Determine the solution set of −x=−8.
A. {8}
B. {8}
C. {8, 8}
D. No solution

Answer 1

The solution set of the equation −x=−8 is {8}, as isolating the variable x gives x = 8. Therefore, the correct answer is B. {8}.

Step-by-step explanation:

To determine the solution set of the equation −x=−8, we need to isolate the variable x on one side of the equation. Doing this, we find that:

x = 8

Therefore, the solution set contains just one number, which is 8. The correct answer is B. {8}, since a solution set is a collection of all the solutions of the equation, and since x has only one value in this case, the set contains only that single number.
