Question

verify that a-(-b)=a+b if a = -13 and b= 12​

Answer 1

Answer:

-1

Step-by-step explanation:

a-(-b) = -13 -(-12)

-13 +12 = -1

(as when 2 negative signs are separated by a bracket, whenever the bracket is opened it turns into positive sign.

a+b

-13 + 12 = -1

therefore, a-(-b) = a+b

Answer 2

Answer:

a-(-b) = a+b

if ,

a = -13

b = 12

Step-by-step explanation:

LHS :-

=> a-(-b) = -13-(-12)

= -13+12

= -1

RHS:-

=> a+b = -13+12

= -1

Therefore the LHS = RHS
