When do u know which method works best?idk with different problems?
I understand this book Bt need more time to practice
There is personal preference but you can also look at the equations and see which would be easiest. We are going to have a whole lesson on this Tuesday.
Elimination method is pretty easy. I finally got to watch the video after NJHS and auditions... :)
I don't get home to do the elimination with both variables on the same side of the equal sign I am confused on the homework but I tried 4
no word from the sponser??? are there any situations on the homework that there is no solution??? can you recognize if it is going to be parallel or constant????
Just like when solving with substitution, if both variables disappear and the remaining numbers do not equal, it means no solution. And if the remaining numbers do equal, it means infinite solutions.
Comment- This video helped so much! It really clarified the exact question I had! While doing my homework, I went through the video step-by-step to solve! Thanks!
Question- I think I understand why...but why exactly do you have to multiply the ENTIRE equation when trying to make a number so that you can cancel it out? Why not just multiply everything that is on that SIDE of the equation?
That's great to hear!
For your question, think about a regular equation.
3+4 = 7
now if I add 5 to the left side it wont be equal anymore
3+4+5 = 7 <not true!
but if I add 5 to BOTH sides, then it stays equal
3+4+5 = 7+5
The same if I multiply one side by 2, I have to multiply both sides by 2. And since the 3+4 was there first, it is written as 2(3+4)
2(3+4) = 2(7)
Now I could add that 3+4 or distribute the 2
2(3) + 2(4) = 2(7)
6 + 8 = 14
The same EQUALITY PROPERTY applies when there are variables
3x + 7 = 10
can be changed to
2(3x + 7) = 2(10)
Remember the calculator container? If you take out a calculator on one side, it wont be balanced, so you have to take out a calculator on the other side also to make it balanced.
this is way easier than the sub method
Hello, it's me.
These vids are much easier to understand then class itself. Thanks for taking time out of your days of to make them for us. Much Appreciated and those big numbers always make me feel like i did something wrong.
You're welcome. I am glad they help!
I like this better than the substitution method
This method is the easiest for me to use so far :D
no why did I put that there
This website doesnt like me
I understand this better now
just watched makes a lot of sense now to plug it back in
good job on the videos
cool video it make more since thanks mr bigsby
One video I'm missing
I'm asking this question because
1. Extra credit (PLEASE 😭)
2. I need help
Question: When we work with fractions do we follow the same steps? Because my tutor is helping me with fractions and I'm really confused. I always end up with repeating decimals. I know we did this in class but I had my group members help me (a lot). Please answer me because I'm struggling a lot with this.
