ok so rearrange things so that it says 6-d=20, then subtract six from each side to get -d=20-6, then subtract 6 from 20 to get -d=-14, then multiply both sides by -1 to get rid of the negative sign in front of the d since a variable cannot be a negative thus making your answer -14 or letter D. :) ❤❤❤❤
hope this helps
Put all the components into the right place, and you will get
6-d=20,
then you subtract six from each side to get,
-d=20-6,
and again subtract 6 from 20.
Now you will get,
-14 or option D.
You were correct when you checked your answer.
