Im starting to think that this board is infected with High schoolers

Solve this in terms of Y

and no this is not homework I got this out of an old algebra textbook

if you can't so that then you don't belong on /sci/

i dont even care.
we cant prove either way.

[Anonymous No.2585174]

inb4idiot but how exactly do you solve that in terms of y? there isn't even a y in the equation to being with

[Anonymous No.2585176]

>>2585174
the first term is 4y
learn to read >.<

[Anonymous No.2585177]

Wow. How long it took to evaluate this?

[Anonymous No.2585180]

Did you miss the 4y?

[Anonymous No.2585181]

OP is a faggot

[Anonymous No.2585183]

firstly I'd common denomintor the shit out of it, then cross multiply like a don, and finally subtract and divide all the shit that isn't a y.

effort doing it though.

<div class="math">
y = \frac{(d - \frac{m}{c}) \cdot (2a+x)}{4}
y = \frac{1}{4} (d-\frac{m}{c})(2a+x)
</div>

Any 15-year-old can do this.

[EK !EKFQOBUFnQ No.2585231]

>>2585203
yeh.
but fractions look nicer.
also, you need to put 'y=' on one side, or it isn't even an equation.

apart from that, you get the same as me >>2585121

[Anonymous No.2585239]

<span class="math"> y = C + C_1 x [/spoiler]

finding out <span class="math"> C, C_1 [/spoiler] is left as an exercise to the reader

>>2585223
>Any 15-year-old can do this.

yes, but you cant.

the second line in the equation is wrong, you put an extra Y where there should not be one.

[Rainbow Dash !!pGgXu8jfKhv No.2585244]

>>2585231
Yeah I started typing it out as fractions but hen I realized that when I got to c i would have /c/2 or /c/4 and that doesn't look nice.

But yeah yours is nicer. I just don't know how to use latex T.T

[Anonymous No.2585245]

LaTeX is pronounced as Latex glove right

[EK !EKFQOBUFnQ No.2585254]

>>2585245
probably.
ive heard it said 'lay-tek' before though.

[Rainbow Dash !!pGgXu8jfKhv No.2585256]

>>2585240
No he just messed up with the latex. Those are 2 different steps. He didn't put a space between the 2 equations

[Anonymous No.2585263]

>>2585245
I've generally heard it pronounced "luh-TEK", but here are some options.

[EK !EKFQOBUFnQ No.2585267]

>>2585244
you should learn the basics. it is useful.

with ['math'] brackets around. use:
\frac{INSERT NUMERATOR HERE}{INSERT DENOMINATOR HERE}

here is a list of other symbols.
e.g. \pi makes the symbol for pi.

e.g <span class="math"> \pi [/spoiler]
and you can double click on any line of latex to see the code for it, so you can learn to replicate it.

[Anonymous No.2585268]

The correct pronunciation, as Wikipedia will probably beat you over the head with, is Lay-tek. "tex" is actually written in Greek, τεχ. χ = chi = pronounced /kh/.

Why are Americans always so confused by other languages?

[Anonymous No.2585271]

its actually

[Anonymous No.2585276]

>>2585268
You beat me to it. So I'll just provide source

http://www.tex.ac.uk/cgi-bin/texfaq2html?label=TeXpronounce

since word LaTeX is derived from TeX, pronouncing it the same as in "latex glove" is terribly terribly wrong and you would sound like an idiot if you'd ever say it aloud

[EK !EKFQOBUFnQ No.2585277]

>>2585256
he is still an idiot.
the next line was rewriting the whole thing, but just changing a 1/4 at the start to dropping a 4 down as a global denominator instead.

...totally unnecessary.

Yes thats correct
