Final Temperature

A 13.0 g block of iron at 95 degrees Celsius is dropped into 80.0 g of water at 15 degrees Celcius. What is the final temperature (degrees celsius) of the iron/water mixture?
Given
m = 13 g of Fe
m2 = 80 g of H2O
T1 = 95 degrees celsius
T2 = 10 degrees celsius
cFe = 0.444
cH2O = 0.418
QH2O - QFe
mH2OcH2O(Tf - TH2O)
Thats what I have so far what needs to be my next step?

Remember that q = m c (T
final
-T
initial
).
The amount of heat lost by the iron is equal to the amount of heat gained by the water. Can you set up an equation to represent this mathematically, then solve for T
f
?
