solve it pls by steps

HW. A section of a composite wall with the dimensions shown in Fig. (1), has uniform temperatures of 200 C and 50 C over the left and the right surfaces, respectively. If the thermal conductivities of the wall materials are: ka=70 W/m K, kB = 60W/m K, kc = 40W/m K, and kp=20W/m K, determine the rate of heat transfer through this section of the wall and the temperatures at the interfaces.
