Woops sorry for double post
Hey, I'm new on this forum.
Just started a college math course this semester and I realized I was VERY rusty since I havent done math in the last 4 years.
Working on what should be ''easy'' problems before the real thing starts and I seem to be stuck on that. If any of you could help me out with a step by step simplification.
I'm probably only missing a small thing and can't get the the correct answer which should be 12x-5.
Thanks in advance!
I would like to remind you of BEDMAS which list the importance of in order of operations BracketsExponentsDivisionMultiplicanAdditionSubtraction. However Multiplication/Division and Addition/Subtraction are interchangeable in BEDMAS, meaning that you can do division first or multiplication.
first we do what is in the brackets, expand out -(x-3) by multiplying each term by -1.

Do the multiplication, 3(4x+3) by multiplying 3 by each term.
