Question

Auditions for a play in New York were held with 100 men and women trying out for the lead singer position. If twice the number of men less three times the number of women is equal to 20, how many women auditioned?

Answer 1

The first equation is

m + w = 100

What do you get for the second equation?

Answer 2

m+w=100--->m=100-w
2m-3w=20--->2(100-w)-3w=20
200-2w-3w=20
5w=180
w=36
