Let us denote the number of boys in the glee club with X and the number of girls with Y.There are 84 students in the glee club, which means that the following equation can be written:X+Y=84We also now that there are 12 more boys than girls, so:X=Y+12We can rewrite the first equation like:(Y+12)+Y=842Y+12=842Y=62Y=62/2=31X=31+12=43So, the ratio of the number of girls to the number of boys is: Y/X=31/43

PLEASE HELP ASAP! DUE SOON PLEASE SHOW YOUR WORK
viktelen [127]

Answer:

So for the first one the first ting u have to do is FLIP the equation so---> X-12=y

Then you have to add 12 to BOTH sides----> x-12+12=y+12

<u><em>So your answer for X ----> x=y+12</em></u>

<u><em>For Y on the first equation it is--->y=x-12</em></u>      (Just flipped and the sign changed)

For the second equation we are gonna solve for Y first.

The first thing u want to do is divide both sides by -3 so it will look like this

-3y/-3    =   2x/+36/-3

<u><em>So Y will equal-----> -2/3x- 12</em></u>

Now we are going to do the X part

So fist FLIP the equation---->      2x+36=  -3y

The add -36 to both sides-----> 2x+36+-36=-3y+-36

Last step you have to divide both sides by 2

So that would be----> 2x/2= -3y-3

<u><em>Your final result will be----> x=-3/2y-18</em></u>

I hope this helped you out (:::::::
