    PrntScrn is one of those buttons that noone ever ueses up there by the scroll lock and the sysRq keys. It takes a screenshot like this that you can open in paint and send as a picture. and no email....

    when these equations are equal, you get parallel lines

    do you know how to make these equal? or rather, solve for x?

    ok.... what we have here a an = sign meaning that the equation needs to be balanced at all times, whatever you add or take away from one side has to be done to the other too....does that make sense?

    ok, so 7x-3x=? and -10+70=80... I'm lost

    good...good.. that means that 4x = 80 right? now divide both sides by 4 and waht do we end up with?

    if you have 7 xs and take 3 xs away, that just leaves us 4 xs...or 4x

    now we want to get rid of that 4 that is hugging next to the x. we do that by dividing it by 4 to get: (4/4)x = 80/4 whats this equal?

    thats correct, so 1 x = 20 and thats the answer

    So you would alway divide in the third step?

    i think of it this way, when you are trying to get a variable..like x.... all by itself on one side, I first send the neighbors home....and that is anything that is attached by addition or subtraction to our variable...whats next is the more intimate stuff, the ''spouse'' i call it.... you get rid of it by multiplying by its reciprocal.... by whatever that number is turned upside down.

    the reciprocal of 4 is 1/4 4 times 1/4 = 4/4 = 1

    the recirocal of 1/6 is 6; 1/6 times 6 = 6/6 = 1
