Question

What is the solution of the equation -16 = 1/2s - 20?

a) s = 4
b) s = -48
c) s = -8
d) s = 12

Answer 1

To solve the equation -16 = 1/2s - 20, we add 20 to both sides and then multiply by 2, resulting in s = 8, which is not listed among the provided answers, suggesting an error.

Step-by-step explanation:

The solution of the equation -16 = 1/2s - 20 is found by first isolating the variable s on one side of the equation. To do this, add 20 to both sides of the equation to get 4 = 1/2s. Then, multiply both sides by 2 to solve for s, which results in s = 8. However, none of the provided options match this solution, suggesting a possible mistake in either the equation provided or the answer choices.
