Step-by-step explanation:
Let's solve this by elimination, then substitution.
x= Adult ticket
y= Student ticket
First day: 14x + 8y = 376
Second day: 7x + 11y = 272:
14x+8y=376
7x+11y=272
Divide 14x+8y=376 by -2:
-7x+-4y=-188
7x+11y=272
Eliminate both -7x and 7x:
-4y=-188
11y=272:
Add all numbers:
7y=84
Divide both sides by 7/ divide 84 by 7:
y=12
Now substitute y into one of the equations:
7x+11y=272:
7x+11(12)=272
Simplify:
7x+132=272
Subtract both sides by 132:
7x=140
Divide both sides by 7 (140/7):
x=20
Adult Tickets: $20
Student Tickets: $12
