Can a positive and negative number be equivalent

Yep.

Step-by-step explanation:

Negative numbers are under zero (see the number line for an increasingly complete clarification of this). Additionally, something contrary to any negative number is a positive number. ... The accompanying blended numbers are for the most part equivalent: - 1/6, - (1/6), (- 7)/6, 7/(- 6), and - 7/6.

Hope this helps!
