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:
Hope this helps! :3
