Answer:

x = 5

Explanation:

Let the number be x

Translating the word expression into an algebraic equation;


-1 * (1+7x) - 6[(-7-x)] = 36

Simplifying the equation, we have;


-1 - 7x + 42 + 6x = 36


41 - x = 36

Rearranging the equation, we have;


x = 41 - 36

x = 5

Therefore, the number is 5.
