a math club has 40 members. the number of girls is 5 less than 2 times the number of boys. how many members are boys? how many members are girls?
----------------------
Members equation: b + g = 40 members
Girls equation:: g = 2b - 5
--------
Substitute for "g" and solve for "b":
40-b = 2b - 5
3b = 45
b = 15 (# of boys)
---
g = 2b-5 = 25 (# of girls)
