$$\begin{array}{rrl}\\
(y/3)+5&=&-9\qquad(take\;away\;5)\\
(y/3)&=&-4\qquad(times\;3)\\
y&=&-12\\
\end{array}$$

Thanks for your great explanation!

$$\begin {array}{rrl}
3x-7&=&2\times-4\
3x-3&=&2\times\
3x&=&-6\
-6/div3&=&x
x&=&-2
\end{array}$$

\begin {array}{rrl}3x-7&=&2\times-4\3x-3&=&2\times\3x&=&-6\-6/div3&=&xx&=&-2\end{array}

.....

Dbg you hae found the mean.

Median = middle

82 , 83 , 85 , 85

The median is in between 85 and 83

If we have two numbers in median we add them together then divide by two too find the centre.

$${\mathtt{83}}{\mathtt{\,\small\textbf+\,}}{\mathtt{85}} = {\mathtt{168}}$$

$${\frac{{\mathtt{168}}}{{\mathtt{2}}}} = {\mathtt{84}}$$

84 is your median.

Ok ill try when I get home.

But, when I took out the six its because I had done +6 I think. But as it's in brackets you can't do that you have to also take out the x.

Sorry, like I said I was never taught this well, I have never understood it properly .

Interesting, thank you Heather.

It seems you are the brains of the TitaniumArmy, that is if you are part of it, i assumed as you have a close relation with Titanium.

$$\begin array{rrl}
(5x+6)\div12&=&-2\\
(5x)\div12&=&4\\
5x&=&48
\end{array}$$

\begin array{rrl}
(5x+6)\div12&=&-2\\
(5x)\div12&=&4\\
5x&=&48
\end{array}

The equations where you have to make it as small as possible.

I recently learnt that and I'm not doing the best.

Well, honestly i think it's the teacher...I have two, one that (like you) has a lot of passion in me being a good a mathematician

The other teacher's teaching technique in my opinion, is bad... He's foreign, and he just gives the equations and shows the step,  but he doesn't explain well.

Talking of maths teachers, my math teacher told me I'm getting invited to this University for an award on June 3rd for winning this maths competition i was a few out of 40,000+ !    

I haven't learnt a lot but i'll try.

Neu what?

That is the most ridiculous thing I've ever heard of. What have you done to this forum.

It's funny how you 'bann' people for several hours, at first i thought iit's a nice joke to play even though i spoke right in front of your face.

But if you're serious...It doesn't work.

Fighting won't anything or gain anything particularly for you, i see you have your 4 squad (?)  army. Nice, but what are you going to do with them apart from ruining this amazing math forum.

Its frustrating, rude and selfish!

Its GNO, she's the one who has acess to take that many point away...

Oh, and look who's giving 5 points to them selves!

Yeah, the way to a lot of point without effort and letting other's lose points.

Its just her habit guys.
