so we need to get x by itself what is the first thing step we can do in making x a loner?

anonymous · Answer

subtract 4 from each side..

anonymous · Answer

Well both 4s so... subtract 8 from each side.

anonymous · Answer

but that second 4 is under the sqrt sign so we can't yet just move that first 4. the next step is to get the sqrt sign the fsk out of there

anonymous · Answer

Yes. So it looks like: 
$$\sqrt{6x+4} =12$$

anonymous · Answer

Correct?

anonymous · Answer

well you added 4 on the right side and took away 4 on the left. remember an equation means that pellet here = pellet here. So what you do to one side you do to the other. so nope not correct. But close

anonymous · Answer

Sorry that was me being a dork xD let me redo that: 
$$\sqrt{6x+4} =4$$

anonymous · Answer
