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 How many people who downloaded songs from the site that month downloaded Q Sam's latest single?

    x = 0.6x + 384 if this ur equation and i set x = 0 then 0=384.. doesnt make sense

    seems a little odd given the words that you have \(x\) on both sides of the equal sign, but no matter, you can go ahead a solve anyway

    \[x = 0.6x + 38\\ .4x=384\\ x=384\div .4=3840\div 4=960\]

    you start with \[x=.6x+384\] to get \(x\) on one side of the equal sign, subtract \(.6x\) from both sides \[x=.6x+384\\x-.6x=684\\.4x=384\]

    if the decimal annoys you you can always multiply both sides by 10 and get \[10x=6x+3840\\ 4x=6840\\x=3840\div 4\]

    maybe they had a problem like "solve for \(x\), \( 2x=6x+5\) " but maybe not
