Question

-104=8x what is x ????

Answer 1

-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.

Answer 2

`-104=8x \\ \\ - (104)/(8) = x \ / \ divide \ each \ side \ by \ 8 \\ \\ -13 = x \ / \ simplify \\ \\ x = -13 \ / \ switch \ solution \ around \\ \\`

The final result is, x = -13.
