Which expression has the same value as the one below? 8+ [4+(-9)]

12+(-9)

-129

-4+(-9)

4+(-9)

Given :

Some expression :

8+ [4+(-9)]  ,  12+(-9)  , -129  , -4+(-9)   ,4+(-9) .

To Find :

Which expression have same value .

a )

8 + [ 4 + ( -9) ]

= 8+(4-9) = 8 -5 = 3 .

b )

12+(-9)

= 12 - 9 = 3

c )

-129

d )

-4 + ( -9 )

= -13

e )

4+(-9)

= -5

Therefore , the expression 8+ [4+(-9)] and 12+(-9) have same value .

Hence , this is the required solution .
