Thanks so much! Literally, you're the best teacher! I've never seen the "I" placeholder used before, but it makes so much sense. This helped me with my homework! Longtime subscriber, your videos are helping me push through.

thank your mister. our prof solving these problems by changing the differential in order to not to introduce new variables but it only makes things more confusing

Tony Angelo - by multiplying 25 / 16 by the reciprocal of 16 / 25 you get 1 and you do the same to the rest of the equation to balance it

It's so hard to not mess up when doing these types of problems :(

Why did we have a 9/9 on the left side making it 25/9 +9/9 = 34/9. What is the principle behind it?

[tonyangelo]

Why do you multiply by the reciprocal?
