I’ve been learning this for about a week in class and didn’t get it and this guy teaches me in 4 minutes
My teacher is getting paid to teach me this in an hour and this guy sums it up in 4 minutes for free
It looked complicated at first yet it turned out to be easy
Thanks.

At 2:36 why do u multiply by 2
I know this was ages ago but it's so there's a -2 and a +2 due to the Y aspect
@@NESIceHockeyThis reply helped me with my question, thank you.❤
@@sokimari9891it’s been two years and I don’t even remember anything about that class. Glad I could help tho… you will NEVER use that stuff again lol
can you tell us when it is better/easier to use the elimination method vs the substitution method?
Good question Kevin. If you already have one of the variables by itself on one side of the equation then I would use substitution. If both variables are on one side of the equation in both equating I would use elimination...
Thx Daddy
Thanks, Mario.
You’re welcome Grace!
Watching this before my test! Hope it helps
Good luck!
How did you get x = 2 from 21x = 42?
divide by 21, 42/21x = x=2
Very helpful, thanks
How do u know what to multiply by?
Here is a more recent video I did on the topic that should explain it better for you: Solving Systems of Linear Equations Using Substitution and Elimination with 2 Equations 2 Variables
