solve for x
You can square both sides, to start with.
oh do you just need x by itself? i thought you wanted like actual values. ok phew
getting x by itself is getting the actual values.
no i meant like a numerical value
it would be a numerical value. Determined by unknown d and variable y.
i have know idea what to do
did you square both sides?
what did you get
what do you mean? well i got 4x-y=9d^2
i need to solve for x
well squaring both sides would get you (squareroot 4x-y) ^2 = (3d)^2
how do you get ^2
and so now you're squaring a square root. it's like (squareroot of 4)^2 square root of 4 is 2 right? so it would be 2^2 which is 4 again. so basically if you're squaring a square root, you're not really doing anything so the square root and square cancel each other out if that makes sense
oh ^2 means sqaure
so you get how to square both sides then?
idk this is my first time doing this or a problem like this
oh ok well have you done questions like this: x^2 = 25
that would be 5 ya
yeah this question is pretty much the same thing
so in the x^2=25 you basically square rooted both sides. so square root of x^2 = square root of 25 x=5 but it in this question you have to square both sides, give it another try
so you square the 3d
yup and also the sqrt 4x-y
so would it be 9d
9d^2 but yeah
kk then what do i do
did you also square the other side?
so would it be 16x-y^2
no because remember its squareroot of 4x-y already. so squaring it gets you squareroot of 4x-y times squareroot of 4x-y which is just 4x-y
so it stays the same
can you solve it now? you just have to get x by itself
would the square roots still be there
so it would look like 4x-y=9d
ok well you should also probably ask your teacher this too cause in math it's really important to know why things happen
kk i dont have a teacher
oh...how does that work?
well my mom is my teacher but my mom is in the hospital
how do i get x by it's self
sorry if you dont mind me asking, what grade are you in? like technically, like your age
14 in 9
so in an equation whatever you do to one side, you have to do to another. so you could add y to both sides which would get you 4x by itself
sorry again, (none of my business i know) but why don't you go to school?
so what i got was 4x=9dy drama and lot of fighting
that's right except that it's d^2 not just d
oh, well i'm sorry. hope it works out, whatever it is
thank you well we are having hard times my bf just got put in jail for a year
aww :/ Imagine all the people, living life in peace... *swaying to the awesome music* sorry, only thing i could think of
It's good that you're doing math and stuff though
lol thank you hes only 15
i thought you couldn't go to jail unless you're an adult? well i suppose different countries
ya well i live in hawaii so there is only two jails and one prison and a whole lot of bad kids they do what they have to
ohh the kids do what they have to?
ya well know that i look back at what happened it is his own problem
oh. well anyways good luck. time heals
ya kk so know what do i do with 4x=9d^2y
oh i thought you'd solved it. well think about, this time entire time you've been doing things to both sides. how would you get x by itself this time?
you divide 4 on both sides
because what happens on one side you do to the other
yeah! exactly! :D good job
thank you so it would be 2.25 d^2y
wait what? so i had 4x=9d^2 + y and so x= (9d^2 + y)/4
ya and that is what i did then i divided 9/4=2.25
