Question

Tell whether each number is a solution to the problem modeled by the following equation.

Mystery Number: Five more than −8 times a number is 29. What is the number?



Let the mystery number be represented by n. The equation is 5+(−8)n = 29.



Is 3 a solution to the equation?


Is −4 a solution to the equation?

Answer 1

Neither are a solution.

Explanation:

The thing is, -4 * -8= 32+5 =37, and you're looking for 29.

3*-8=-24+5=19. If you meant to put positive 8 and not negative, then 3 would be right, but other than that, neither are correct.
