Question

Verify a-(-b)=a+b, for the following values of a and b (i) a=2, b= -6

Answer 1

Step-by-step explanation:

$\mathtt{a - ( - b)} = 2 - (- ( - 6))$

$\mathtt{ = 2 - 6 = - 4}$

$\mathtt{and \: the \: same \: way}$

$\mathtt{a + b = 2 + ( - 6) = 2 - 6 = - 4}$

hence verified..

Answer 2

Step-by-step explanation:

LHS. RHS

a-(-b). a+b

=2-(-(-6). = 2+(-6)

=2-(+6). = 2-6

=2-6. = -4

=-4

Thus L.H.S =R.H.S

Hope you get answer.
