start working on this bit by bit. you can take 4 off each side to begin with and it gives you x/3 -2/3 = 3

2. anonymous

remember - what you do to one side, you must do to the other. what would your next step be?

3. Republican31

Okay. I was starting to go in the direction of converting the 4 into a fraction.

4. Republican31

x-2/3 = 3?

Next would I add 2 to both sides? I don't think that makes sense but I'm not sure. Or should I be dividing 3 by 3?

7. anonymous

close, but you'd do the 2/3. add 2/3 to each side.

8. Republican31

x=3 2/3?

$4+\frac{ x }{ 3 }-\frac{ 2 }{ 3 }=7$$\frac{ x }{ 3 }-\frac{ 2 }{ 3 } = 3$$\frac{ x }{ 3 } = 3\frac{ 2 }{ 3 } = \frac{ 11 }{ 3 }$$x=11$

Up until the third line.

12. anonymous

3rd line you add 2/3 to both sides to cancel out the 2/3 on the x/3 side

13. Republican31

Or nevermind, I see now.

Thank you both! But I can't give best response to both of you...

15. anonymous

Alright! Thank you both very much! There might be a couple more questions coming from me tonight just so you know.
