X=number of senior tickets
y=number of student tickets

1st day
7x+1y=101

2nd day
7x+12y=134

easy, we can eliminate the x's

multiply first equation by -1

-7x-1y=-101
<u>7x+12y=134 +</u>
0x+11y=33

11y=33
divide by 11 both sides
y=3
sub back

7x+y=101
7x+3=101
minus 3 both sides
7x=98
divide both sides by 7
x=14

senior tickets cost $14
student tickets cost $3
that sounds unfair
