1. The problem statement, all variables and given/known data

Hi,

I am in dire need of your help. I can't seem to solve this problem:

Here's my trial on this: While it is a common knowledge that Martians are green and have seven heads, few people realize that a Martian has eleven eyes. At a recent party, while I was conversing with a Martian, I innocently remarked that if one-half of the Martians at the party suddenly became Earthlings (while the other half remained Martians), there would be 295 eyes at the party. Somewhat offended, the Martian noted that if one-half of the Earthlings at the party became Martians (while the other half stayed Earthlings), there would be 410 heads at the party. How many Martians and how many Earthlings were at the party?

7h+11e= martians

1/2(7h+11e) +1/2=295 eyes

1/2 + 1/2(7h+11e)= 410 heads

Then do the subtraction method from the linear equation to find one variable and go from there. The thing is I don't think my two equations are right because if I do that then all of the stuff on the left side will be 0 which is justly wrong.

CAN ANYONE HELP ME GET THOSE TWO EQUATIONS PLEASE? I know that 7h+11e= martians though. I just don't know how to go further.

Every little help counts. Please.

ANOTHER QUESTION: (that I need help on)

For years George and Martha Huber supplemented their modest income by

blackmailing their neighbours. Neither of them made very much money at this until

two years ago, when Martha found out about Susan Black’s sordid past. That year,

George and Martha together extorted $108,000. The following year Revenue

Canada found out about Martha, so although she took in the same amount of

money, she had to pay half of it in taxes. Meanwhile, George’s activities went

unnoticed, and he took in $3000 more than he had the year before. Together they

netted $65,000. If Susan was paying Martha $75,000, how much Martha was

getting from other neighbours?

My tackle on this one:

G= George's share of the money

M= Martha's share of the money

(3000+G) + (1/2M)=108,000

G+M= 65,000

I don't know if those equations are right. PLEASE HELP!
