Answer:

x = -8

Step-by-step explanation:

To find x, we need to isolate it. So first, let's subtract 2.6 from both sides to get rid of it on the side with x:

3.2x+2.6-2.6=-23-2.6

3.2x+0=-25.6

3.2x=-25.6

Now, divide both sides by 3.2 (because notice how we are multiplying it right now - so we need to undo that, and so we do the inverse operation of division):

\frac{3.2x}{3.2} = \frac{-25.6}{3.2}

Notice how we are left with 1x on the left which is x, so we have successfully isolated x:

x = -\frac{25.6}{3.2} = -8

So, x = -8. Hope it makes sense, ask me any questions you may have! :)
