X = advance
y= same day
x+y=70
30x+15y=1650
--------------------------
30x+15y=1650
- x+y=70 (x15) -> 15x+15y=1050
--------------------------
30x+15y=1650
-15x+15y=1050
--------------------------
15x=600
x=600/15
x=40
so now u can insert the price of x AKA the price of the advanced ticket to find our the price of the same day ticket.
x+y=70
so
40+ y=70
y=70-40
y=30
x = advance =40
y= same day =30
