Using MS Excel, solve the temperature distribution for the aluminum plate described in the table and figure below. Assume the plate thickness to be $1$ cm $($in $Z$ direction$)$ and the heat transfer to be in the XY plane only. Assume the thermal conductivity of aluminum to be $237\frac{W}{m}C.$

Please describe this process or link too an example. I have tried using Slover but it is too many constraints, variables, etc.
