## anonymous one year ago FAN AND MEDAL!!! Solve for x: 2 over 3 (x - 4) = 2x. A) 2 B) -2 C) -8 D) -4

1. anonymous

What is your understanding of this question?

2. anonymous

Don't let the variables on both sides throw you off :)

3. anonymous

I tried it but the fractions are throwing me off.

4. anonymous

Ah, it's always those pesky fractions… remember to get rid of them, take it's inverse on both sides of the equation! Like this:

5. anonymous

What do you think an inverse operation means?

6. anonymous

idk

7. anonymous

It means to multiply the opposite (or reciprocal) of the fraction on both sides.

8. anonymous

For example… if I were trying to get rid of 1/2, I would multiply it by 2/1 on both sides. Is it clear so far?

9. anonymous

Yes So it is now 2x - 8 = 6x ?

10. anonymous

How did you get -8 and 6x?

11. anonymous

Is it B?

13. anonymous

How did you get that answer?

14. anonymous

Plugged in? ;)

15. anonymous

I don't know how to explain how I got it. I just solved for x.

16. anonymous

Then, great job… that is correct.

Thanks!
