mean of x1 + x2+.....+ xn/n=x                                    ..........(1)

mean of ax1 + ax2 +........+axn/n

            = a(x1 + x2 +.....xn)/n                                         ........(2)
              
             putting eq (1) in eq (2)     

           =  ax                          
              
            hope that helps you!!
