Negative ten times a number minus five equals negative eleven times the same number.

121

Step-by-step explanation:

-10 x 0.6 = -6.

-6 - 5 = -11

-11 x -11 = 121

-10n - 5 = -11n

n = 5

Step-by-step explanation:

Times = multiplied by

Minus = subtract

Let n = the number

Negative ten times a number:  -10 x n = -10n

minus five:  - 5

equals:  =

eleven times the same number: 11 x n = 11n

Therefore:  -10n - 5 = -11n

To solve  -10n - 5 = -11n

Add 11n to both sides:

⇒ -10n - 5 + 11n = -11n + 11n

⇒  n - 5 = 0

Add 5 to both sides:

⇒  n - 5 + 5 = 0 + 5

⇒  n = 5
