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
explanation: 1/3=2/6 is multiplied by 2 in the numarator and the denominator but in 1/6=3/6 you multiply only the numerator by 3
L + F + G = 51
F = 3L...F = 3(G + 4)....F = 3G + 12
L = G + 4
(G + 4) + (3G + 12) + G = 51
5G + 16 = 51
5G = 51 - 16
5G = 35
G = 35/5
G = 7 <=== Greg sold 7
L = G + 4...L = 7 + 4....L = 11 <== Lin sold 11
F = 3G + 12.....F = 3(7) + 21....F = 21 + 12....F = 33 <== Fran sold 33
