Answer:
-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
