Question

Solving the equation

Answer 1

`\huge\boxed{-1}`

Explanation:

In order to solve an equation, our goal is to isolate the variable on one side of the equation.

As of now, we have
`-x = 28`

This is the exact same thing as
`-1x = 28`, since a negative sign also means you multiply it by -1.

We want to divide both sides by the coefficient on x so that we have x, positive and isolated, on one side of the equation.

Therefore we want to divide by -1.

Hope this helped!

Answer 2

-1

Explanation:

We need to isolate x.

When we do so, we want it to be a positive term.

-x = 28

To get the x term positive, we divide both sides by -1.

x = -28
