Question

Verify that a+b=b+a for the following
a= -2/9 , b= -4/3
No spam plz ​

Answer 1

Step-by-step explanation:

LHS :

a + b

= ( - 2 / 9 ) + ( - 4 / 3 )

= ( - 2 / 9 ) + ( - 12 / 9 )

= ( - 2 - 12 ) / 9

= - 14 / 9

RHS :

b + a

= ( - 4 / 3 ) + ( - 2 / 9 )

= ( - 12 / 9 ) + ( - 2 / 9 )

= ( - 12 - 2 ) / 9

= - 14 / 9

LHS = RHS

Hence verified.

Answer 2

Answer:

LHS = a + b

= -2/9 + (-4/3)

= -2/9 -4/3

= (-2 -12)/9. ( Taking LCM as 9)

-14/9

RHS = b+a

= -4/3 + (-2/9)

= -4/3 -2/9

= (-12-2)/9. ( Taking LCM as 9)

= -14/9

Hence LHS= RHS.

Hope this helps ☺️
