Question

combining like terms N- 4- 9

I got -13n

Answer 1

n-13

Answer 2

n-13=0 so, therefore, n=13

Answer 3

No, it's not n=13

Answer 4

show me how nis not = to 13?

Answer 5

becuase they didnt say that it equals to zero.. or a number or whatever... so you can't solve it!

Answer 6

it doesn't say anything equals zero, so all we can do is put N-13 is the simplified form of the above

Answer 7

the answer is
N-13
in simplified form

Answer 8

^ exactly :)

Answer 9

true, if they are not asking for it to be solved.

Answer 10

ok my first answer was -13n so I need to keep the n in front

Answer 11

it says simplyfy each expression

Answer 12

Question Turing I was always taught that the letter goes on the right. What makes this different?

Answer 13

what you need to to is only mess with the numbers that have like terms:
examples:
5a+6a=11a (because they both have an "a" we can combine them)
5x-12+6=5x+6 (we have to put together the parts that have no x)

2x+3y+4x+5y=(2x+4x)+(3y+5y)=6x+8y

This last example really shows what combining like terms is all about: putting the parts that have an x with the other parts that have an x, and those with a y with the rest of those that also have a y. That's what "like terms" means :)

Answer 14

It makes no difference the order of the expressions, it's just convention to put variables (letters) in the front, but that may need to change in order to solve a problem, so don't get locked into it.

Answer 15

ok thank you
