The winning times in the 500 meter speed skating world championships for men are approximated by m= 46 - 0.1y and for women by w=57 - 0.2y, where y is the time in years since 1900(so y=5 is 1905, for example) and m and w are the times in seconds. Using these approximations in what year will the mens' and women's times be equal?

Just solve for m=w:
m = w
46 - 0.1y = 57 - 0.2y
0.1y = 11
y = 110
"Year" 110 is 110+1900, which equals 2010.

You need to solve for Y
Set up the equation so that Men will equal Women:
57-0.2y=46-0.1y
Can you solve this now?

46-.1y=57-.2y
.1y=11
y=110
1900 +110 =2010 the two will be equal.
