Using Elimination to Solve Systems

👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves making the coefficient of one of the variables to be equal in all the equations that make up the system, in order to eliminate the variable using subtraction (or addition as the case may be). The coefficients can be made equal by multiplying the entire equation with a number which when multiplied to the coefficient of the variable to be eliminated gives the LCM of the coefficients of the variable to be eliminated in all the equations. Then we solve for the remaining variable(s).

After we have obtained the solution{s} for the remaining variable(s), we substitute the obtained solution into any of the original equations to obtain the solution of the eliminated variable.

Who else is watching this bc their teacher doesn’t know how to teach

[dubdub]

the kids in his class don’t realize how lucky they are

[pedrocodile]

Bro this teacher is 💯 times better than all of my math teachers

[FertileHippo]

This guy taught me more in 9 minutes than my math teacher could in 1 hour and 20 minutes. Great job!

[silvanasamson]

who else is in quarantine trying to understand their online math home work...?😭😭

[bassmanism]

I left school 54 years ago and I am trying to understand this, hope I get there.

[steve-vtzu]

I love how he listens to the questions of the class. this dude cares.

[dr.bitchcraft]

Dimitri, Shelley, Ashley, and Sadiq need to pay more attention

[dkuehara]

I went from a 42% to a 92%! The very best I ever did! I can't thank you enough! So grateful for your videos! Mahalo plenty🌸🤙🏼

[Moonstar]

Poor Ashley, Shelly, Dimitri, and Siddiq.

Edit: okay general consensus seems to be Siddiq by a close margin but if we have evidence for other spellings feel free to shoot

If this video or many others was helpful, please consider letting me know with a "Super Thanks" above ⬆. I am able to read and respond to all my messages and thank you so much for your support

[EsperanzaHeidiCampbell]

From this moment forth I am no longer paying attention in math class, THIS is my new teacher, cuz my math teacher doesn't make ANYTHING clear, and shes also really mean to us, constantly treating us like we're stupid, and putting us down and im over it.

POV: You're here because your teacher is bad at teaching

[craigfishcake]

Brave man being filmed. You have demonstrated excellent communication skills, great patience, a full explanation to the class of the subject, and left nothing to guesswork. Good competent teaching.

[cecccEae]

0:22 he's really calling these kids outtt

[astroust]

You saved me, as you apparently did for thousands others. And you were just as much my teacher as my in person instructors. Thank you tons.

[emilymarisol]

Watching this @2am bc i have a final test and my teacher doesn’t explain like him 😖

[rockytablason]

Why -2 and 3?
Variable X is his chosen elimination (3× and 2x).
-2 (3x) = -6×
3 (2x) = 6x, and now you can eliminate it.
You can pick ANY factors. Make sure the factors you going to pick will produce the SAME RESULT but OPPOSITE SIGNS as you MULTIPLY it by CHOSEN VARIABLE so that you can eliminate it and also don't forget to multiply the whole equation by the factors you chose.

I decided to finish my degree after 20+ years out of college. Part of that was taking elementary math (118). Using your videos has been super helpful in that pursuit!
