Question

combining like terms simplify each expression:

15n -19n = -4n

Answer 1

n(15-19) = -4n?

Answer 2

n(15-19) = n(-4)

Answer 3

simplify each expression

Answer 4

15n -19n = -4n
-4n = -4n
this is an identity

Answer 5

jimmyrep am i right?

Answer 6

what you have written is correct - yes
n(15-19) = n(-4)
further simplification gives what i wrote

Answer 7

ok thank you

Answer 8

but that simplification doesnt make sense -4n = -4n
thats just like saying 0 = 0 i dont know maybe im wrong

Answer 9

I am combining like terms and simplifying each expression

Answer 10

well 0 is = 0
15n -19n = -4n is an identity not an equation because it is true for all real values of n

Answer 11

i think his problem says simplify 15n-19n
and he is saying it simplifies to -4n

Answer 12

which is correct

Answer 13

yup

Answer 14

yes that is what i am saying

Answer 15

looks like i wasn't wrong but jimmyrep simplified it better then me :p
