okay
OpenStudy (calculusxy):
Hey @HelpBlahBlahBlah !
OpenStudy (anonymous):
do the equation backwards
OpenStudy (calculusxy):
Your first and foremost step is to combine the like terms. Even by doing distributive property, you will have new terms being made.

PEMDAS IS CORRECT
Nnesha (nnesha):
distribute meaning multiply everything which is inside the parentheses by outside term
2(x-9)
OpenStudy (anonymous):
Aka the P Pemdas
OpenStudy (helpblahblahblah):
