Females—x:
x + 2x + 20 = 110
3x = 90
x = 30

Males:
= 2(30) + 20
= 60 + 20
= 80

Answer (1): 80 males

Checking:
80 - 2(110 - 80) = 20
80 - 2(30) = 20
80 - 60 = 20
20 = 20
-----------
No. of men—x:
2x - 3(100 - x) = 20
2x - 300 + 3x = 20
5x = 320
x = 64

Answer (2): 64 men

Checking:
2(64) - 3(100 - 64) = 20
128 - 3(36) = 20
128 - 108 = 20
20 = 20

@Bri_Love were you doing a different problem as an example?

whpalmer4 · Answer

Problem statement says that there are a total of 80 employees, not 110.

anonymous · Answer

Nope that should be the answer.

Its 20

whpalmer4 · Answer

No.

M = number of males
F = number of females
M+F = 80

M = 2*F + 20
2*F + 20 + F = 80
3*F = 60
F = 20
M = 80-F = 80 - 20 = 60
