Transposing Algebra Scribe for February 4, 2009

Wednesday, February 4, 2009
Today in math class, Mr. Harbeck taught us how to transpose algebra. We learned that to transpose algebra you have to:


  • Transport letters/variables to the left and numbers/constants to the right.

For example:













  • After moving the letters/variables to the left, you have to cancel one of the variables by using the opposite to cancel it.
  • Then you have to balance it by doing the same thing on the other variable.

For example:














  • After that, you do the same thing for the numbers/constants.

For example:












  • After, you solve it to get a one step equation.

For example:

































* Remember that when you verify it, you use the original question.

Mr. Harbeck said that this is grade 9 stuff but we have to learn it so we will be ready for grade 9. This won't be part of the exam but there will be quizzes.

Homework: Page 52 in purple booklet and write 3 examples of combining like terms at the top and 3 examples of transposing algebra at the bottom of multi-colored booklet ( the very last page, color green).

I did the first 2 questions from page 52 in the purple booklet:
S.) Is the example on top.
A.) 8y - 3 = 2y + 15
-2y + 3 = -2y + 3
One-step equation:
6y = 18
6y/6 = 18/6
y = 3
Verify:
8y -3 = 2y + 15
8(3) -3 = 2(3) + 15
24 - 3 = 15 + 6
21 = 21

    Very good scribe Karen! Just a few things to fix. Okay, the first thing you should change is the "After moving the letters/variables to the left" (which can be found after your first picture) to "To move the letters/variables to the left...". Also, you might want to add a picture for your second example (question S) and maybe add another example as well. I suggest doing a question that has both transposing and the distributive property in it because this might confuse some people (C would be a good one to do). Other than that, your scribe was great!

    Awesome scribe Karen!! I don't see any major mistakes at all and I don't think there are any minor mistakes either, but just a few things you can maybe fix for people to understand it better. Such as question "S", the question is kind of not aligned correctly but that doesn't really make a big difference, most people might understand it anyway. Oh yeah, I think the multicolor booklet is due tomorrow, but I'm not for sure on that, you could include in your scribe saying that the multicolor booklet is due soon, and that it is worth 50 marks. That's all, great scribe :D!
