First, you set up your equation.

let's now get rid of the negative 4 and move it to the other side so we can set up another equation.

Now, we can cross multiply to get x

x= 28

(The picture should help you a little bit :) )

Hope this helps!

First multiply both sides by 7

Your equation now looks like this:

x-28=0

Now move the constant to the other side causing it to change signs

The negative now becomes a positive

x=28

Now you are left with your answer:

x=28

Hope this helps! :3
