I’m on a time limit
solve for c
6.5c - 2.5c + 9 = -7
give an example of how you got the answer!
: )

6.5c - 2.5c + 9 = -7

4.0c+9= -7

move +9 to the other side

sign changes from +9 to -9

4c+9-9= -7-9

4c= -16

divide by 4 for both sides

4c/4= -16/4

c= -4

Answer : c= -4

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
