6c + 3t = 4800
8c + t = 4600 .....multiply by -3
----------------
6c + 3t = 4800
-24c - 3t = - 13800
---------------add
-18c = - 9000
c = -9000/-18
c = 500...so each car is 500

8c + t = 4600
8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600...and each truck is 600

selling 2 cars and 3 trucks...
2(500) + 3(600) = 1000 + 1800 = 2800 <==
