36 = 3x-4 40 = 3x x = 40 /3
so what i didnt get, was even though the 3x was square root, you still divide. I understand you have to simplify.
because 3x is like 3*x, so you do the opposite on the other side of the equation.

sqrt(3x) -4 = 6 ; +4 each side sqrt(3x) = 10 ; ^2 both sides 3x = 100 ; /3 both sides x = 100/3
ack... lol
:)
I get too confused on simple mathematics. Im sorry. lol
i don't sure the function is sqrt (3x) or sqrt (3x-4), thats why parentheses are important
It is sqrt(3x) -4
i dont get 300/6 tho...which is the 'right' answer lol
Yeah, I dont know where I got 300/6
probably off a sheet of paper you wadded up and threw in the trash where it belonged? :)
Probably, I might have did 100/3 just typo maybe ? lol.
I really appreciate the help, tremendously.
you know; ive answered over 300 questions and still havent gotten the 1st answering machine badge? ...
:)
How do I give a badge.... i would give it to you if I could lol. This is my first time using this site.
badges are given thru performing certain tasks; not handed out really; medals for good answers can be given by the masses tho ;)
I see, well I wish you the best of luck :) You'll definitely get it in time. I really appreciated the help. Seriously.

you might have to hit f5 to refresh your browser to see any 'good answer' buttons next to our names tho
Why is it, when i try it myself... now i am getting 4/3? I am just trying to do it and get the right answer :/
nevermind, i see. 4+6. Ah. lol
:)
now how would I write this out to double check? would it be.... \[\sqrt{3(100/3)}-4=6 then multiply both sides by 3?\]
please disregard the one-wordness there lol
add 4 to both sides first
then square both sides
i understand the method. I get confused with fractions
ack....
so wait....
3*(100/3) = 100 sqrt(100 = 10)
sqrt(100)=10 10-4 = 6 is true
OOOOO
wow...
Wow... i feel stupid at the moment :/
