Default Some math help please.
Sounds silly and probably obvious but I need some help.. (Answering my friends math problem actually. She turned to me for advice but I couldn't help.. even though I'm getting A's and A*'s and she's on B/C level :L)

There are men and octopuses in a tank. In the tank there are a total of 11 heads and 52 legs. How many men and octopuses are there? And you have to find out using simultaneous equations.

It's been about a year and a half since we studied them, but I got up to here and then got stuck. Could someone please finish the workings and I'll probably get it then

X = Number of Men
Y = Number of Octopuses

X+Y=11
2X+8Y=52

...



Please help :L

Well...

I worked out what numbers added together to make 11, and then tried doing the second sum

I dont know how to work algebra out right, always had a cheat way

omgz i did this today!!

X+Y=11 (equation 1)
2X+8Y=52 (equation 2)

X+Y=11 (x 2)
2X+2Y=22 (equation 3)

2X+2Y=22 (
2X+8Y = 52

(equation 2 - equation 3)
2X+8Y = 52 - 2X+2Y=22

6Y = 30 (divide by 6)
Y = 5

sorry had to use my book took awhile

and too find X u have to do what y is in the formula so

X+Y=11
(-5)
X = 6

so vicky is wrong as x = 6 and y = 5

Who needs algebra, when it's logical and obvious that there are 6 men and 5 octupuses?

I really don't get why we have to learn algebra, I swear you don't use it unless you're gonna be a maths teacher or something.
