X=4
cross multiply
3x=12
x=4
Ok so basically, the number of student tickets is 3x, where x=the number of adult tickets sold. And we know that s(for student tickets)+x=480 total tickets sold. So if we replace s with 3x we have 3x+x=480, or 4x=480. We divide by 4 and get x=120, which is the amount of adult tickets sold.
Answer:
put x=1/2, you will get, r(1/2)=20*1/2-89
=10-89= -70.
