I hope this helps you
Where's the question?
First you cross multiply.
2*(b-4)=6b
Then distribute the 2.
2b-8=6b
Minus 2b from each side.
-8=4b
Divide each side by 4.
-2=b
So -2 is your answer.
Look at 36/3 = 12.
So let's try 12 along with the one before it and the one after it.
10 + 12 + 14 = 36
yay !
The answer to this question is D.
