I'm trying to help my niece I need to explain but I completely forgot hot to do this :P
7+2x=4x-3 +3 +3 10+2x=4x -2x= -2x 10=2x 2 2 x=5 is that right?
Do we subtract 7s
im stupid thats wrong I think
Can u explain it ?
Well sure, I can explain. Do you know PEMDAS?
You are using the idea of "balance"
Order of operations.
Well yeah, balance what you do to one side you do to the other..
Charro you need to try and isolate the variable
to do this add 3 to both sides
subtract 2x from both sides because you only want the X on one side.
@AcidRa1n Why don't you let @charro ask questions?
Sorry I was trying to explain it to him. He asked if I could explain it
I'm kinda excited because it's something I actually know how to do >.< :P
skull can you help me on my question?
@acid thanks..I'm trying to refresh my memory. I don't want to look like the dorky aunt lol
let @charro finish...any questions?
Well she subtracted and somehowgot the same answer acid did
yes you can go either way. In PEMDAS you could sometimes subtract before you add. it still works out
yeah! lol thanks
I'm new to this..how can I get a hold of you again
put your mouse over my name and fan me
then you can either use @acidra1n in a question or send me a private message
Cool thanks again
