30

Answer 1

I would be dead without your guyzzz help . <3

Answer 2

ok let women = x There x amount of women
and let men = (90 - x) since there are 90 ppl in total

Answer 3

make a system of equations!
let x=#of men
and y=#of women
so...
x+y=90
2x-3y=30

Answer 4

ohh yaaa u can solve it that way

Answer 5

whats the next step?

Answer 6

so lets use substitution to solve this
make x=90-y and sub that in for x into 2x-3y=30 so...
2(90-y)-3y=30
180-2y-3y=30
-5y=-150
y=30
so 30 women auditioned

Answer 7

and if you also need to find out the #of men who auditioned then just simply sub in 30 for y into x+y=90 to get your answer :)
