Question

For a = (- 9) , b =( -7 ) and c = 6 , verify whether a + ( b + c ) = ( a + b ) + c

Answer 1

Step-by-step explanation:

devide whole equation to LHS and RHS thn

a+(b+c) is LHS and (a+b)+c is RHS

thn first take a+(b+c) and thn first solve bracket part -7+6=-1

thn add a thn it will bcm -9+(-1)=-10 is LHS answer.thn go to RHS

solve bracket part-9+(-7)=-16.

thn add cthn it will bcm-16+6=-10.RHS answer.

it means LHS=RHS
