Any time I have searched how to do something math related, your videos are always the easiest to understand, and I've never had to watch something more than a two times. Thank you so much!!

  • @sed192
    @sed192 10 років тому +1

    Wait, when you distributed the x into the parenthesis x-(12-x) How did you get x. If its a product its x^2 and if its a difference its 2x, but not x. How is that accomplished?

    • @brianmclogan
      @brianmclogan  10 років тому +2

      Sorry for your confusion, this video was created to solve using elimination and I went on a tangent also showing substitution. I am not sure where you obtained x^2. When I simplified I had to add x + x which is 2x. Is there something else I am missing that you are referring to?

    • @chrisstanton3632
      @chrisstanton3632 3 роки тому

      I was with you until I realized they're distributing the negative and not X.

  • @onlineshopunbox
    @onlineshopunbox 4 роки тому

    I got the answer and its 4 and 8 but what I think is that it says that "The difference of THE SAME two numbers are -4"? Can you explain to. 4 and 8 are not the same numbers

    An individual has two low-interest loans, one at 4% interest and the other at 6% interest. The amount borrowed at 6% is $250 more than the amount borrowed at 4%. If the total interest for one year is $165, how much money is borrowed at each rate?

    A corner store sells two kinds of baked goods: cakes and pies. A cake costs $6 and a pie costs $5. In one day,
    the store sold 7 baked goods for a total of $40. How many cakes did they sell?

    • @brianmclogan
      @brianmclogan  8 років тому +2

      6x+5y=$40, x+y=7 x=of cakes sold, y=#of pies sold, not use substitution or elimination to solve

    • @jackgoodwin7673
      @jackgoodwin7673 5 років тому

      you have to multiply the equation by a negative
      eg.
      x+y=12
      x+y=-4 x-1 = -x+(-y)=4
      x+y=12
      -x+(-y)=4
      12/4=3

  • @omega7654
    @omega7654 6 років тому +2

    Wrong. No word problem can be answer without a word answer. Since this problem doesn't really tell a story, its still a word problem so they answer can literally be "The numbers are 4 and 8". This is really critical to your grade because if you don't put this on a test you will be marked wrong.
