In 2005, there were 66,000 new cases of skin cancer in the United States. Men represented 10,000 more cases than women. How many new cases of skin cancer were there for men and for women?

Lets use this two variables.

m = men

w = women

m = w + 10000

Solve for the equation:

m + w = 60,0000

Substitute for m and the equation becomes:

(w + 10000) + w = 60000

Now solve for w.

2w + 10000 = 60000

2w = 60000 - 10000

2w = 50000

w = 25000

since  m = w + 10000, substitute the amount for w

m  = 25000 + 10000

m = 35000

Final answer:

For men = 35000

For women = 25000
