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

Solve for : x + 20 / 2 = 3x
amistre64
  • amistre64
use your grouping symbols correctly ... im assuming (x+20) is on top?
anonymous
  • anonymous
yes
amistre64
  • amistre64
what is your thoughts then, how would you try to work this?
anonymous

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.
amistre64
  • amistre64
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
amistre64
  • amistre64
i would start out by multiplying both sides by that denominator
anonymous
  • anonymous
So multiply both sides by 2 and get rid of the 2 on the first side?
amistre64
  • amistre64
yep x+20 = 2(3x) x+20 = 6x ... now what are your thoughts?
anonymous
  • anonymous
There is an x on both sides, so you have to get them onto one side. Which side do I choose?
amistre64
  • amistre64
either side works ... personally is move the leftside over but it doesnt matter
anonymous

20 = 5x?
amistre64
  • amistre64
subtraction UNDOES addition soo x+20 = 6x -x -x ----------- 20 = 5x yes, now what is our x value?
anonymous
  • anonymous
4

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.

3x + 3 = -2x + 2 + 6 now what?
anonymous
  • anonymous
ANYWAYS
anonymous
  • anonymous
3x + 3 = -2x + 2 + 6 3x + 3 = -2x + 8 3x = -2x + 5?
amistre64
  • amistre64
so far so good, now add 2x to get rid of the -2x and we should be good
anonymous
  • anonymous
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
