Raphael, not bad! It looks like you’ve made the same algebra mistake and somehow un-did it too.
For T(1), you moved your parentheses over and so you’re missing an e^k factor on the right side; it should read 152=T_m +(212-T_m)e^(-k). A similar thing happened when you were writing out T(2). This gives you two equations in two variables: T_m (which you’re trying to find) and k.
