    FBT and Mr. Witt is awesome!!! I am 45 and starting life over, while back in college. I have not practiced math(College Algebra) in 25 yrs. I spent a lot of time trying to figure out my professors teachings with UA-cam searches(zombies). I just found you- with finals coming up. I learned everything in 3 days watching you, than in 4 months of listening to him and I enjoy it!!! Get those arrows poppin'!!! Thank You, old dog, learning new tricks.

    Question in 5:42 ho did u get 40/5 ? I got confused
    Is it like u multiplied 2 (-8/5) + 8
    I get the -16/5 but for the 40/5 did u multiply 5 and 8 then put the same denominator?

      @FortBendTutoring  4 роки тому

      Hello MsDera426! I rewrote 8 as 8/1, then multiplied the numerator and denominator by 5 to get an equivalent fraction 40/5. This was all done to get fractions with the same denominator so that I could add them. ua-cam.com/video/ZhKAXZU0tyQ/v-deo.html

    • @FortBendTutoring
      @FortBendTutoring  Рік тому

      Hello Odell! The 5y is the sum of 4y and y. When combining like terms, you add the coefficients of the terms. In this case you’re adding the 4 in 4y and the 1 in 1y.

    8:46 We will also need infinitely many solutions for our answer to check if we got the answer correct or not, like when we are converting from one form to another. If we have one solution or no solution, then we made some mistake that has to be fixed. Otherwise, if we have infinitely many solutions to the system, then we are AOK.

  • @uncrownedkingzz
    @uncrownedkingzz 10 років тому +1

    I think what you are doing is great. the way you explains things in the sense that it is absolute helps me understand and accept what is being taught. Any chance you could allow a pause or prompt on maybe the third or fourth problem to allow time for someone to try the problem out? Or designate a problem for us to work out? thanks Mr. Whitt!!

    • @FortBendTutoring
      @FortBendTutoring  10 років тому

      Great suggestion! I'll consider it. In the meantime, if the next problem looks similar press pause and try to solve it or do a similar odd problem in your textbook. Most likely you'll find the odd answers in the back of your text. Thanks for the feedback!

    • @FortBendTutoring
      @FortBendTutoring  8 років тому

      +MsDera426 In that instance, there wasn't an "easiest" variable to solve for. Just know that some choose based on the number of steps and others choose a variable to solve for based on how small the coefficient is. It's a personal choice and "easy" is relative to each individual's belief as to what "easy" is. You'll know which variable is easiest for you with experience. Until then any variable you isolate will help solve the problem. In the meantime, you can use this as a guide as to which variable to pick.

    Hello Mr. Whitt! I’m just curious, For multiplying decimals and subtracting. On problem 6 towards the end, How did you get 1.6? Did you multiply the 2 by the 8 but brought down the decimal to separate them and how did you get .4 from 1.6-2 wouldnt it just be 1.4?

    • @FortBendTutoring
      @FortBendTutoring  3 роки тому

      I multiplied -2 times -0.8 to get 1.6. I believe you may have missed the -0.8 because it’s written as (-.8).
