    • @danielledawson5702
      @danielledawson5702 4 роки тому +1

      He starts to explain it at 7:40 but I get why you're confused as I was too, so I'll try to put it in to words and hope I don't make it worse! You have to think of each add and subtract symbol as just telling you whether the number that comes after it is positive or negative. Then in the final equation the '+' symbol is just being used like 'and'. So think of this equation as being 'negative 3x & positive 1 & positive 2x & negative 5' so when you put positive 2x on to negative 3x you get negative 1x (+2x + -3x = -1x) and when you put plus 1 on to negative 5 it becomes negative 4 (+1 + -5 = -4) so altogether you get the sum -1x + -4 (this last + is just like an & so think of it as -1x & -4) and because the x is only one he shortens it to just -x . Then in the following equations you don't need the + that is being used as '&' so you can shorten it further by taking that out. ((Remember that the x is like an unknown number so if you went on to work that out then that is the number you would be adding or subtracting from. So if for example you were told that -x was actually -1 then it would be -1 - 4 = -5 but in this case we don't know so we just have -x - 4)) Hope that is possible to make sense of and good luck to anyone reading this!

      @leyaadams1939 5 років тому

      That’s just how the problem was set. Basically since the problem was 5x+3x-7+9 you just break it down. Since 5x+3x makes 8x that part of the equation is taken care of so now u have to do -7+9 and since there’s more positives then negatives it’ll equal 2 so you get 8x+2
