I need some extra brainpower for this: 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 (WHAT IVE WORKED OUT): X = 100% Of people who downloaded songs from a website 0.6 [times] X = 60% 60% + 384 = 100% Choices: How many people who downloaded songs from the site that month downloaded Q Sam's latest single? A. 576 B. 240 C. 144 D. 960

    x = 0.6x + 384 -.6x -.6x ----------------- .4x = 384 what should x be?

    Solve for : x + 20 / 2 = 3x

    use your grouping symbols correctly ... im assuming (x+20) is on top?

    I know that you first have to single x out onto 1 side of the line, but what confuses me is the division thing. I know with division you have to find a Least common denominator, but since there is only one division problem here, Im clueless as how to go on.

    whatever we do to one side, we do to the other .... A/2 = B ... in order to UNDO division, we multiply 2A/2 = 2B A = 2B

    i would start out by multiplying both sides by that denominator

    So multiply both sides by 2 and get rid of the 2 on the first side?

    yep x+20 = 2(3x) x+20 = 6x ... now what are your thoughts?

    There is an x on both sides, so you have to get them onto one side. Which side do I choose?

    subtraction UNDOES addition soo x+20 = 6x -x -x ----------- 20 = 5x yes, now what is our x value?

    i few things wrong with this ... some would contend that this is cheating on an exam; but the more important thing is that you have posted personal information that is contained in the picture.

    so far so good, now add 2x to get rid of the -2x and we should be good

    3(x + 1) = −2(x − 1) + 6. 3x + 3 = -2x + 2 + 6 3x + 3 = -2x + 8 3x = -2x + 5? +2x +2x 5x = 5 x = 1 Thanks pal! :D
