Eleven times the sum of a number and six is - 66 what's the equation

n - a number

the sum of a number and six: n + 6

eleven times the sum of a number and six: 11 · (n + 6)

Eleven times the sum of a number and six is - 66:

11 · (n + 6) = - 66

11 (n + 6) = - 66 divide both sides by 11

n + 6 = - 6 subtract 6 from both sides

n = - 12
