-104 = 8x. The x is being multiplied by 8, so to undo the multiplication divide both sides of the equal sign by 8. 8x/8 = x and -104/8 = -13 so x = -13.

$-104=8x \\ \\ - \frac{104}{8} = x \ / \ divide \ each \ side \ by \ 8 \\ \\ -13 = x \ / \ simplify \\ \\ x = -13 \ / \ switch \ solution \ around \\ \\$

The final result is, x = -13.
