    -5

    Step-by-step explanation:

    Let the number be n

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

    5n - 5 = 6n

    -5 = 6n - 5n

    n = - 5

    - 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
