If eleven subtracted from eleven times a number is -66, the unknown number is -5
Given the data in the question;
First we translate the statement into an algebraic expression and solve for the unknown number.
Let x represent the unknown number.
Translation
Now, we combine.
11x - 11 = - 66
Solve for x
Add 11 to both sides
11x - 11 + 11 = - 66 + 11
11x = -55
x = -55/11
x = -5
Therefore, if eleven subtracted from eleven times a number is -66, the unknown number is -5
