Can someone help me with the equation in the picture below.

Answer:
x=3
Step-by-step explanation:
First, you would distribute the 4 to the (x-3), giving you 2x-6+4x-12
From there combine like terms, 2x+4x=6x, -6+-12=-18
6x+-18=0
6x=18
divide both side by 6, and you get 3=x!
I hope that all makes sense :)
