    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?

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

    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

    I like the male/female breakdown in your answer better, though :-)
