Algebraic Word Problems

Algebra brings us a new and interesting way to see how math can solve real-world problems! We just have to learn how to construct equations that say something meaningful about a given situation, and then solve them using the techniques we already know. Learn all about how to do this here!

I’m currently studying for my college entrance tests and Mathematics is my waterloo 😔 I’ve been having a difficult time catching up with my classmates because I’ve already forgotten all the basics (e.g., percentage to decimals, even the simple algebraic word problems). I am sooo thankful that I found your channel! When I started planning to study for math, I was at lost because I didn’t know where to start; but when I saw your videos, it carved a clear path for me and it made it easier for me to learn math. Thank you very much for dedicating your time and effort into sharing these teachings. I really really appreciate them! ❤️

We are damn lucky to come across your channel! Maths was something that I wasn't able to get in to, Always struggled with it solving during my exams. So glad that I found you! Honestly such a life saver. Cheers!

I can't thank you enough, Professor Dave. I can't believe I'm enjoying learning maths once again. I literally have been watching your videos for several hours straight.
I'm watching other videos of yours Street I'm done with the maths playlist and I'm recommending your channel to my friends ASAP.
Much love from Nigeria.

This made me realize how inefficient the education is in my country. We were always taught (especially in math subjects) in a single dimension, or in out of context.

They just drop numbers out of nowhere, don't give real life relatable applications of the equation. Then scare you psychologically calling Algebra a rite of passage, like a bunch of buffoon bullies.

They do not display Math in its beauty and don't deserve to teach Math.

If I was taught in this way, the Algebra makes sense and my study on this topic would have been a lot of easier! Thank you for the life changing video.

These are amazing! Would it be possible to have a link at the end of each lesson with more exercises? It would help sealing the knowledge in :)

If anyones struggling, I recommend writing every piece of information the question gives you on a piece of paper, and the equation will come to you. The best way to learn conversion to equations is through experience. Much like learning any new language.

This is AMAZING! I am going into middle school and this is helping me sooo much!

Thank you for these life changing videos! I've been struggling with both english and math and it's helping a lot

Thank you🙏 professor Dave god bless you and I can do now my homework again thank you

Готовлюсь к ЕГЭ по профильной математике по этому плейлисту)) Афигеть как круто всё объясняет..

This is really going to help me figure out the value of x if x=what is received from DMX.

manifesting na sana ganito ka easy yung mga algebraic expression word problems ang lumabas sa test✨️✨️

R=red marbles
B=black marbles

R=2B-5
2B-5+B=70
3B-5=70
3B=75
B=25

R=2B-5
R=2(25)-5
R=45

I'm gonna check now
Edit: i did it right 😁

i so confused at the answer of comprehension, but after analyzing, i finally understood now
lets call the red marbles as R and black marbles as B.
Since if we add the number of red and black marbles, it would be equal to 70
so it would be R + B = 70
the number of R is 5 less than twice the number of black marbles,
so the equation would be R = 2B - 5, since we still dont know the value of R, lets subtitute the equation to R+B=70,
which becomes (2B-5)+B=70
simplifying by combining terms, turning into 3B-5=70.
so:
for B
3B-5=70
3B=75
B=25

Since we know now B is 25, we can subtitute 25 in equation of R which is:
R=2B-5
R=2(25)-5
R=50-5
R=45

so
R+B=70
45+25=70

I guess I need to study english first to understand this lesson... >.<

This is why I hate bloody word problems. And when I say hate I am using the true and pedantic definition for that word. For that multiples of three problem I had no idea where to start but once you showed just one of the potential ages in the formula I was able to write the rest of it.

Hello profesor Dave thank you for learning to algebra world problem

[tramarthomas]

solving the word problems gave me the same feeling I have when solving rubiks cubes, I use algorithms I learned online to make solving them a lot easier and it makes for a calming yet somewhat challenging experience. i love it!
