2t + 3j = 14 ....multiply by -3
6t + 5j = 28
--------------
-6t - 9j = - 42 (result of multiplying by -3)
6t + 5j = 28
------------add
-4j = - 14
j = -14/-4
j = 3.50
2t + 3j = 14
2t + 3(3.50) = 14
2t + 10.50 = 14
2t = 14 - 10.50
2t = 3.50
t = 3.50/2
t = 1.75
so the trail mix (t) costs 1.75 per lb and the jellybeans (j) costs 3.50 per lb
