do you need help?

anonymous · Answer

I did 2 because if 2/3 * 2/1 = 4/3

4/3 + 8/3 = 12/3 --> 4

4 = 2^2

4 = 4 therefore its ture but I used the answer options, can you explain how to get it if I didn't have the options

phi · Answer

I don't know a simple way to solve this equation... but you can test each of the choices and pick the one (if any) that is a solution.  In other words, replace x with the "answer" and see if you get a true equation.

I wanted to use a legit method so it not considered "cheating" I know for sure its 2, but isn't there a way to get x without using the options?

phi · Answer

You would use numerical methods, or graphing...
Here is a graph
y = ⅔ x + 8/3
and 
y= 2^x

as you can see there are two solutions.

You could use a "root-finding" algorithm such as Newton-Raphson... a technique that uses calculus and a computer...

Lol this is 9th grade Alg. I Honors "." I don't think I can use that method yet >.>

phi · Answer

Yes, I was guessing that was the case.  This is one of those problems where you test the proposed solutions (just like you did).

anonymous · Answer

Oh so i was suppose to use the choices? ;O

anonymous · Answer

Yep should've graphed it lo thnx for your help :)
