find the final equilibirum temperature when 10.0 g of milk at 10.0degC is added to 1.60*10^2 g of coffee with a temperatrure of 90.0degC. Assume the specific heats of coffee and milk are the same as for water (Cp,w=4.19J/g*degC) and disregard the heat capacity of the container


massmilk*cmilk*(Tf-10)+masscoffee(ccoffee)(Tf-90)=0
please show me in simple steps how to solve for Tf

thanks a lot
