Question

How do you solve `-2x + 6= 18`?

Answer 1

`x=-6`

Explanation:

Our goal for this problem is to get isolate `x`.

to do this we start by subtracting `6` from both sides of the equation. (in other words, do `6-6` and `18-6`)

we now get `-2x=12`

Or final step is to divide both sides of the equation by -2 (we do this so `x` is by itself on one side of the equals sign, but whatever we do to one side, we must do to the other, that is why we also divide `12` by `-2` )

With this, we get `x=-6` which is our answer.

Hope this helps!
