Question
Add the following: $7abc, -5abc, 9abc, -8abc$
✓
Answer
Adding the given terms,
We have, $7abc + (-5abc) + (9abc) + (-8abc) $
$= 7abc - 5abc + 9abc - 8abc$
$ = (7 - 5 + 9 - 8)abc$
$ = (16 - 13)abc$
$ = 3abc$
We have, $7abc + (-5abc) + (9abc) + (-8abc) $
$= 7abc - 5abc + 9abc - 8abc$
$ = (7 - 5 + 9 - 8)abc$
$ = (16 - 13)abc$
$ = 3abc$
