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 " .
