    Thank you so much! You make these topics so easy to understand. I have to do so much self studying because my algebra teacher isn’t very good at explaining. Your videos are really helping me out!😭

      When you do systems of equations can one of the ways to do it work every single time for every single system of equations problem?

    Thank you for this, I have to finish a test tomorrow and I always solve for y in the standard form which always gives me a fraction. I was so stressed out but now I know u can solve for x in the standard form an still get the same anser. Thank you so much you really helped me

  • @ABCDEFGH637
    @ABCDEFGH637 5 ปีที่แล้ว

    i was so confused by you, I would rather go direct
    take 2nd equation x + 2y = 10, then x = 10-2y, apply to equation (1), then 4(10-2y) + 3y = 10, then 40-8y+3y=10, then 40-5y=10, then -5y=10-40= -30, so -5y=-30, -y=-6, y=6, apply y=6 to equation (2), x+12=10, x=10-12, x= -2

    • @brianmclogan
      @brianmclogan  7 ปีที่แล้ว +1

      I would not say the hardest but would agree elimination would be preferred, however the video was teaching those substitution

    Hi mr brian . I wanted to wright you on twitter but you have turned messages off. I have a question about factorials . For example : (m-n)!=m!-n!

  • @littlebigcomrade
    @littlebigcomrade 5 ปีที่แล้ว

    I help need with substitution when there are fractional exponents.
    For example:
    3y^-2 + y^-1 + 4 = 0
