I've been working through several of your recent videos and was able to dredge up the knowledge needed to get this correct! I really like your channel as I struggled with math most of my life and now decades later am able to get through some of the things I used to have trouble with by watching your videos!

Today I was looking at a lot of algebra. Some of YouTube's videos are uploaded about what I'm looking at. It is amazing that Mr. Brian McLagan and Premath Guy a few of them. They also teach about quadratic formulas, elimination, and how to factor in algebra. A lot of knowledge is gathered so. But you make it look easy peasy. you, sir!thanks

The answer to this proportion is: x=5, and x=-4. Thank you for the great review of factoring a trinomial and solving a proportion. I really appreciate this review.

quick way to answer : ( x -1 ) + 5 = 4 + x = 0 ==> x = - 4
and also ( x - 1 ) - 4 = - ( 5 - x ) = 0 ==> x = 5

So the answers are x = -4 or x = 5

Take a survey & see if you can find ANYONE who uses algebra
outside of class.
