pooja195 (pooja195):

Nope they are not like terms what would we add 5 to, to cancel it out so that we have 9x ALONE
OpenStudy (lolipop_drum312):
mmm add it to 32 or 5 itself
pooja195 (pooja195):
good
-32+5=?
OpenStudy (lolipop_drum312):
38
OpenStudy (lolipop_drum312):

That's incorrect
-32+5
now 32+5
pooja195 (pooja195):
*not
OpenStudy (nurali):
1. add 5 both side
2. divide by 9 both side
OpenStudy (1davey29):
@Nurali has it right. You would solve it like a normal "solve for x" problem.
OpenStudy (lolipop_drum312):
sorry lagged....so that would be 9 divided by 10 equals 1?

pooja195 (pooja195):
divide both sides by 9 now 9/9 cancels out
-27/9=?
OpenStudy (lolipop_drum312):
18
pooja195 (pooja195):

a negative divided by a positive is a negative
pooja195 (pooja195):
So what is our final answer?
OpenStudy (lolipop_drum312):
-3?
pooja195 (pooja195):
