Question

Verify that a+ b =b + a by taking
a= 2/3 and b= -3/7

Answer 1

Answer:

hope it helps you

Step-by-step explanation:

2/3 + (-3/7)

2/3 - 3/7

14/21 - 9/21

5/21

-3/7 + 2/4

-9/21 + 14/21

5/21

hence verified a+b = b+a

Answer 2

Step-by-step explanation:

LHS :-

a+b = 2/3 + (- 3/7)

=2/3 - 3/7

= (2*7/3*7) - (3*3/7*3)

= (14-9)/21

= 5/21

RHS

b+a = -3/7 + 2/3

=( -3*3/7*3) + (2*7/3*7)

= (-9 + 14)/21

= 5/21

LHS = RHS

therefore, a+b = b+a
