Question 1091817
6A+1S=23, where A is an adult ticket and S is a student ticket
12A+14S=106
from equation 1, S=23-6A
substitute into equation 2.
12A+14(23-6A)=106
12A+312-84A=106
-72A=-216
A=$3
use that in first equation and get 18+S=23, so S=$5.
check in second equation and 36+70=106
Adult ticket is $3 and student ticket is $5.
