----------------
2t+8c = 445 cents
t = c + 100 cents
------------------------------
Substitute for "t" and solve for "c":
2(c+100) + 8c = 445
-----
2c + 200 + 8c = 445
10c = 245
c = 24.5 cents (price of lb of copper)
----
Solve for "t":
t = c + 100
t = 24.5 + 100
t = 124.5 cents (price of lb of tin)
