Answer:
a=1
Step-by-step explanation:
The answer to this problem is 1. This is the answer because using PEMDAS, you would first have to distribute -3.
So: 9a+ -6a+12=15
Combine like terms:
3a+12=15
Subtract 12 on each side. 3a= 3
Divide 3 on each side.
Hope this helps!! :D
learn it
x=3
simplify first
4-1=3
X+3=6
next you want to get x by itself
X+3-3=6-3
what you do to one side you must do to the other
X=3
not me sorry lol good luck
