At 2:36 why do u multiply by 2

[@NESIceHockey]

I know this was ages ago but it's so there's a -2 and a +2 due to the Y aspect

[@sokimari9891]

@@NESIceHockeyThis reply helped me with my question, thank you.❤

[@NESIceHockey]

@@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

[@XCaliKev]

can you tell us when it is better/easier to use the elimination method vs the substitution method?

[@MariosMathTutoring]

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

How did you get x = 2 from 21x = 42?

[@LvnderSoul]

divide by 21, 42/21x = x=2

[@hionaise5677]

Very helpful, thanks

[@ceciliajacqueliine]

How do u know what to multiply by?

[@MariosMathTutoring]

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
