Prove here that L.H.S =R.H.S.a+b =a-(-b)a= 21, b=57

1.	Prove here that L.H.S =R.H.S.a+b =a-(-b)a= 21, b=57
Answer» ANSWER: Even if the values of a and B are not given we can prove it : RHS = a-(-b) = a+b (SINCE - × - would become +) METHOD 2 : by using the values given : LHS = 21+57 = 78 RHS = 21-(-57) = 21+57 = 78 LHS = RHS Hence proved Hope it helps :) Very illogical question but still im answering it

Answer»

Even if the values of a and B are not given we can prove it :

RHS = a-(-b) = a+b (SINCE - × - would become +)

by using the values given :

LHS = 21+57 = 78

RHS = 21-(-57) = 21+57 = 78

LHS = RHS

Hence proved

Hope it helps :)
