Question

The number of women at a training workshops was two less than three times the number of men. If 50 people attended the workshops, how many were women?

Answer 1

Set up a system of equations first

W: number of women
M: number of men

50=w+m
3m-2=w

Solve in by plugging in one equation into the other

50=(3m-2)+m
50=4m-2
52=4m
m=13

So if m=13 plug it bag into one of the two equations at the beginning

50=13+w
W=37 women
