help me PLEASE!
idont get it ... i just know to multiply the first one to the reciprical second one
sooo i get \[\frac{ (3y-9)(15x+90) }{ (x+6)(y-3) }\]
would this be the answer ???? \[\frac{ (45xy-270y-135x-810 }{ (x+6)(y-3) }\]
@jim_thompson5910 @Destinymasha Hello there i was wondering if you can help me confirm my steps to my answer because i am not complete sure about the process
Well the problem is that you are given an equation and not an expression. Are you supposed to solve for x,y,n or d?
i am suppose to find n and d @jim_thompson5910
ok, the first step is to flip the second fraction on the left side and then multiply
yes i got \[\frac{ (3y-9)(15x+90) }{ (x+6)(y-3) }\] @jim_thompson5910
That is incorrect
really .... awww ok let me see what i did
we have this \[\Large \frac{3}{x+6} \div \frac{y-3}{15} = \frac{n}{d}\]
then we flip that second fraction to get this \[\Large \frac{3}{x+6} * \frac{15}{y-3} = \frac{n}{d}\]
Then you just multiply straight across \[\Large \frac{3*5}{(x+6)*(y-3)} = \frac{n}{d}\] \[\Large \frac{15}{(x+6)*(y-3)} = \frac{n}{d}\] and optionally you can expand out (x+6)(y-3) to get xy-3x+6y-18 \[\Large \frac{15}{xy-3x+6y-18} = \frac{n}{d}\]
wait how did 3 and 15 turn to 15 ???
oh my bad lol
I had 3*5 instead of 3*15
so 45 goes up top
oh ok n_n
then my problem was just i over think it and it was simply to multiply across .... thank you
you're welcome
