2(3n - 5) + 4 = 15 -(9n - 4), you will get the equivalent equation 6n - 6 = -9n + 11. True or false

you need to simplify it first... so let's do one equation at a time.|dw:1382401731120:dw|

@cuitiefromthesouth2 does that make sense why you first distribute that?

OpenStudy (anonymous):

6n-10+4

OpenStudy (anonymous):

perfect! so now -10+6= ?

OpenStudy (anonymous):

-4

OpenStudy (anonymous):

correct! but sorry, i wrote that wrong lol but i know you understand that part, so it'd be -10+4 (sorry bout that.. lol) so you've simplified it to this: 6n-6 which matches that first part. now onto the next part
