Answer:

senior tickets are 12

student tickets are 3

Step-by-step explanation:

s= senior

t = student

10s+5t =135

14s + 3t=177



10s+5t =135

divide by 5

2s+t = 27

multiply by -3

-3(2s+t) = -3*27

-6s -3t =-81

add this to 14s+3t=177


-6s -3t =-81

14s + 3t=177

---------------------

8s = 96

divide by 8

s = 12

senior tickets are 8 dollars

2s+t = 27

2(12) +t = 27

24 +t =27

subtract 24

24+t-24 = 27 -24

t =3

student tickets are 3
