Can someone help me with this math problem
Elis [28]

Answer:

C. Divide both sides of the equation by -2.

Step-by-step explanation:

The goal of the equation is to isolate x. In order to do that we have to remove the '-2' by doing the inverse operation. That is the opposite operation, for example addition and subtraction, multiplication and division.

Since x is being multiplied by -2, we do the inverse which is division.

Alexeev081 [22]

Step-by-step explanation:

To make the relationship proportional, he must start with zero balance and then should have deposited $20 every month.
