calculate the final temperature (once the ice has melted) of a mixture made up of initially of 75.0mL liquid water at 29 degrees Celsius and 7.0 g of ice at 0.0 degrees Celsius

I don't understand how to calculate the final temperature, can anyone help. thank you

heat to melt ice + heat to cool water (will be negative) from 29 + heat to heat ice to final T (positive number) = 0
[mass ice x heat fusion] + [mass water x specific heat water x (TfinalTinitial)] + [mass liquid from ice x specific heat water x (TfinalTinitial) = 0
Solve for Tfinal. I get an answer close to 20 C but you need to do it exactly. Check my work.
