Me watching the video "Oh i get it now" also me 10 seconds later "wait, what am i supposed to do again"

I am in my sixties and going to college. Taking pre-calculus this semester has been a challenge specially when you have an instructor who doesn’t explain that clear like you do. Thank you for making math less scary, and thank you for the extra tips you included in your videos.

imagine if this guy was your cousin, brother, uncle, dad, or best friend in your day to day life, that's like a real life cheat code for all your math problems.

Narrator: "now here's the one for you." He really explains like he's talking to the audience. that's the reason i like subscribe and ring the bell to this channel !

Thanks for making this so clear and easy to understand! A lot of people don’t like to explain the small steps in their videos, but you did. So big thanks for that because now I finally understand how to do these types of problems!😄

Your voice is so calming and you go slow enough for me to keep up... Thank you!

[soysan]

I hope you know your videos singlehandedly saved me and lotsa other kids in our grade, , respect

you can also transpose the numbers example 8x + 4y = 40, instead of combining them together you can move the numbers in the equal but if you transposed it pass the equal sign, therefore it can make the number opposite sign and what will happen is instead of 8x -8x + 4y = 40 -8x, it will become 4y = 40 - 8x.

idk if i explained it correctly but it is a easier to trick so it is not complicated

Thank you so much. Every other guide has been about 3 terms, I had no idea what to do when both variables in both equations had terms.

[really]

we had online classes in the morning for the lesson but i slept thru it and now i dont understand so here i am... LMAO hopefully i dont fail.

[jackmason]

Thanks man. You explain much better than the teachers and text books.

[bmmagic]

great teaching! I like this way better than the original way that I learned.

[victorejiofor]

I owe you big time, your step by step explanations has helped me solve a problem that I have been trying to solve for over two hours now. Thanks So Much, Bro

[Timmye]

Thank you you explain everything a million times better than the teachers.

[EmmaTrujillo-ou]

Thanks for making math easier, and giving me a refresher! My EOC is tomorrow and I am LAST minute studying, you are so easy to understand!

[trubbyzambia]

Thanks man you've open up my mind I had no idea how to solve this linear system

[celso_vitorino]

Hello! I'm from Brazil. Your explanation helped me. Thank you and congratulations on the didactics.

[skoptec]

I’m in my unit 3 of geometry and I finally know how to do this, thank you, I won’t be struggling as much

[rehana]

Thanks bro this video is definitely 10x better than a 2 hour long math lesson

[philanidlamini]

Thanks a bunch bro ... tomorrow I'll be writing my grade 12 external maths exam and I'm set with simultaneous equations. 👍👍👍👍
