- anonymous

No, Can I send via email?

- amistre64

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....

- amistre64

windows xp

- amistre64

it should open with my openoffice software, but it aint....

- amistre64

got it...
7x-10 = 3x+70

- amistre64

when these equations are equal, you get parallel lines

- anonymous

ok, because I have snag it on my computer and don't know how to turn it off. Thanks

- amistre64

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

- anonymous

No

- amistre64

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?

- anonymous

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

- amistre64

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

- amistre64

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

- anonymous

I'm with you

- amistre64

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?

- anonymous

20

- amistre64

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

- anonymous

So you would alway divide in the third step?

- amistre64

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.

- amistre64

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

- amistre64

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

- amistre64

make sense?

- anonymous

Cool, I think I got it:) Yes, it make sense now

- amistre64

good :)

- anonymous
