Answers:

1)  The answer is:   [B]:  " 40 " .

2)  The answer is:  [B]:  " 7.5" .


Explanation:


1)  Given:  " w − 8 = 32 " ; Solve for "w" ; 

      w − 8 = 32 ;  

Add "8" to each side of the equation; to isolate "w" on one side of the equation; and to solve for "w" ;

      w − 8 + 8 = 32 + 8 ;
 
 to get:
 
         w = 40 ;  which is:  Answer choice:  [B]:  "40" .


2)  Given:  " n + 8.7 = 16.2 " ; Solve for "n" ;

              n + 8.7 = 16.2 ;

Subtract "8.7" from EACH SIDE of the equation; to isolate "n" on one side of the equation; and to solve for "n" ;

              n + 8.7 − 8.7 = 16.2 − 8.7 ;

to get:    n = 7.5 ;  which is:  Answer choice:  [B]:  " 7.5 " .
