Answer:

x = -2

Step-by-step explanation:

3(-2 - 3x) = -9x - 4 (Given)

3(-2) + 3(-3x) = -9x - 4 (Distributive Property of Equality)

-6 + 9x = -9x - 4 (Simplify)

-6 + 4 -9x= -9x - 4 + 4 (Addition Property of Equality)

-2 + 9x = -9x (Simplify)

-2 + \frac{-9x}{-9} = \frac{-9}{-9} (Division Property of Equality)

-2 = x (Simplify)

x = -2 (Symmetric Property of Equality)

On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.

First, let's find out how much $92 less is:

48 - 92 = -44

We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th.

The correct answer is C. The 14th.

Hope this helps!! :)
