Question

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

Answer 1

121

Explanation:

-10 x 0.6 = -6.

-6 - 5 = -11

-11 x -11 = 121

Answer 2

-10n - 5 = -11n

n = 5

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
