I really need help bad! I am working on ALEKS and I'm not able to finish "MyPie" because I cannot solve any of the equations. I understand the basic concept, but I get confused as to when to add/subtract or when to make a number negative/positive. Here is an example: 6(x-2)=4x+4-6(2x+1)
This is how I attempted to solve it: 6x-12=4x+4-12x-6
6x-12=-8+2
6x-8x=12-2
-2x=10
x=14/-2=7/-1
I know this is wrong because ALEKS allows me to click on "explain" and it will show me the steps and the answer, but it doesn't explain why it makes a number positive or negative or when to add/subtract.
Thank You.
