Question

Tell whether each number is a solution to the problem modeled by the following equation.
Mystery Number:
Six more than -7 times a number is 34. What is the number?
Let the mystery number be represented by n.
The equation is 6 + (-7)n = 34
TRUE or FALSE: The mystery number is -7.

Answer 1

Answer:

False

Step-by-step explanation:

6 + (-7)n = 34

Plug in -7 for n and see if it's true:

6 + (-7)(-7) = 34

6 + 49 = 34

55 = 34

No, it's not true, so the mystery number is not -7.
