Question

- 1/2 x + 3 = -x + 7
can someone explain how to solve this?

luckyness · Answer

Sure! :) But do you have an idea on what it is?

luckyness · Answer

$$\frac{ -1 }{ 2 }x+3=-x+7$$
Okay so this is your equation. 
The first step would be to add x to both sides.

anonymous · Answer

@Luckyness It's either 8, -8, 2, or 1/2. I'm not really sure how to even begin solving this. :/

jdoe0001 · Answer

hint:   multiply both sides by 2

luckyness · Answer

No, you do both by x.

luckyness · Answer

Let me give you an attachment of the steps I am going off of.

anonymous · Answer

@Luckyness okay, thank you.

luckyness · Answer

Okay so these are the steps.

luckyness · Answer

So in the final step it says to solve this:
$$2*(\frac{ 1 }{ 2 }x)=2*4$$

luckyness · Answer

So if you used a calculator and solved that, you would get x.

luckyness · Answer

Also, the answer was in one that you guessed. 
It is between 8 or 1/2. Your guess.

anonymous · Answer

@Luckyness thank you so much! & sorry for not responding, I was doing another question. I'm guessing that it is 8?

luckyness · Answer

Yes, it was 8. :)
