One month, a music site observed that 60% of the people who downloaded songs from its site downloaded Q Sam's latest single. The equation below represents this information, where x represents the total number of people who downloaded songs from the site that month:

x = 0.6x + 384

576

240

144

I'm havin trouble finidng x I thought you just had to do it the traditional way and not have a subsitutuon for x

So, what I did was

take the equation $$x =0.6x + 384$$

I gathered like terms

$$0.4x = 384$$

Then I divided 384 by 0.4

$$\frac{384}{0.4} = 960$$

so there I assumed x was equal to 960

You were correct on the first part, 960 is the answer to the first part of the equation

To prove that, you would have to solve for x

x  = 0.6x + 384

Firstly, multipy both sides by 10

x * 10 = 0.6x + 384 * 10

x * 10 = 6x + 3840

Then subtract 6x on both sides

x * 10 - 6x = 6x + 3840 - 6x

4x = 3840

Then to single out the x on the left divide both sides by 4

$$\frac{4x}{4} = \frac{3840}{4}$$

x = 960

Then since it said 60% downloaded the song you would muliply 960 by 60%

960 * 60% = 576

Hope this Helps ;P

It's so weird though I got 960 wrong do you think it's something in the problem I'm suppose to look for? But also thanks for helping really means alot.

But then it said that 60% of people downloaded the song so you got the first part rigt but you would hav to multiply 960 by 60% which would have gotten you 576.

OOOOOHHH  so thats the problem oh so x is equal to the total people on the store wow missed that thanks alot. and multiplying 60% we multiply 960 by 0.60 rigth?

Yes you could do 0.60 or 0.6 or even 60%
