You can put this solution on YOUR website! In a class of 65 students, the number of females is one fewer than twice the number of males. How many females and how many males are there in the class?
--------------------
Equations:
f + m = 65
f = 2m - 1
------------------
Substitute for "f" and solve for "m":
2m+1 - m = 65
3m = 66
m -= 22 (# of men)
----
solve for "f":
f + m = 65
f + 22 = 65
f = 43 (# of females)
