BD is <u><em>Geometric Mean</em></u>

Add the two expressions.<br><br> −4x+3 and 2x−6<br><br> Enter your answer in the box.
BlackZzzverrR [31]
First, you set your problem up like this: 

-4x+3=2x-6

add 6 to both sides so it looks like this:

-4x+9=2x

add 4x to both sides so it looks like this:

9=6x

divide 6 from both sides so this is your answer:

1.5=x
