The variable is - 1/4

Step-by-step explanation:

First when a variable is revealed next to a number it get multiplied by it. Also the - 3 needs - 2 to become - 5 first you have to turn the 8 into a negative so it is a negative variable. Then you need 2 which is 1/4 of 8 but, since the variable is a negative number it is - 1/4.
