Drake Sawyer · Answer 1

-5

Step-by-step explanation:

Let the number be n

5 (n + (-1)) = 6n

5n - 5 = 6n

-5 = 6n - 5n

n = - 5

Clayton Booker · Answer 2

- 5

Step-by-step explanation:

let the number be n then 5 times the sum of n and - 1 is 5 (n - 1), thus

5 (n - 1) = 6n ← distribute left side

5n - 5 = 6n (subtract 5n from both sides)

- 5 = n

Thus the number is - 5
