Ximena · Answer

Step-by-step explanation:      Given  :   a = (-12)   b = 4  c = (-25)     Solution  :      LHS =a+(b+c)         =(-12)+{4+(-25)}         =(-12)+(4-25)         =(-12)+(-21)         =(-12-21)          =-33   RHS =(a+b) +c         ={(-12)+4}+(-25)         =(-12+4)-25         =(-8-25)          =-33     LHS  =  RHS
