    ok you have to isolate the variable so basically get the the variable on one side with the numbers on the other side 14=8-6r -8 -8 ________ 6=-6r (you would subtract 8 from each side because you have to the the oppisate because 8 is positive on the right side and you want to get the eight on the right side so far do you understand?

    14=8-6r -8 -8 ok which side are we trying to get the eight to in this equation?

    yes and since the eight on the right side is positive you would do the opposite because you want to get rid of it from the right side which would mean cancel it out so 8-8=0 right? that would then mean there would be a 0 on the right side and a zero does not mean anything in this particular equation so you would get rid of it

    then we get 6=-6r make sure you remember to keep the subtraction sign which turns into a negative sign because you did not cancel it out yet

    9+4n=-59 -9 -9 __________ 4n=-68 ok we would subtract 9 from both sides because now in this one we have to get rid of the nine on the left side so 9-9=0 right. The main thing in these types of equations is simplifying and canceling out numbers. Understand this part?

    yes we have to do the opposite in that step but once you get to where it would be for example 4n=8 or 8n=16 you would just divide by the regular number like 4n=8 /4 /4 n=2 03 8n=16 /8 /8 n=2

    now for the next step in the problem we are working on so that leaves us with 4n=-68 /4 /4 _________ n=-17 Now we divide four on both sides to get the 4 off of the variable because division un does multiplication

    okay so if a number we trying to get rid of is negative... do we add it to the other side ... do we subtract all the time

    if the number is negative we add if it is positive we subtract but remember that only goes for addition and subtraction

    as i showed in the examples: 4n=8 /4 /4 n=3 or another example -5n=10 /-5 /-5 n=-2 it only work for s and a because usually in m and d the numbers are next to variables which mean 1 times a if it is 1a and i don't why but that is just how it is :p

    it doesn't matter if you change the fractions because eventually they allsimplify down to the same thing and makes sure both the top and bottom are in times by the same number for example in 3/4 i times it by two because you want the bottom number a 8 so i times it by 2 so two times 3 is six and 4 times 2 is 8 andddd i was explaining by the way

    the easiest way is pick a number that all of the denominators can turn into in this case it would be 8

    6/8-4/8n=5/8 -6/8 -6/8 (do the opposite) ________________\ -4/8n=-1/8 (simplify and keeps the subtraction sign which turns to engative cuz not canceled out yet) and then -4/8n=-1/8 /4/8 /4/8 _____________ what do you think n equals ?
