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
