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
