simplify (6a-4)/(7a-5) - 3

OpenStudy (anonymous):

Ok, you are going to multiply your binomials using the foil methode then simplify your answer

OpenStudy (anonymous):

what do you mean? what binomails am I multiplying?! this is an algebraic fraction, 6a -4 over 7a - 5 and subtract 3 from that! i think ur confused...

OpenStudy (anonymous):

ok first you are going to simplify the (6a-4)(7a-5)

OpenStudy (anonymous):

give me a sec to figure out the equation maker

OpenStudy (anonymous):

no im not supposed to multiply it, it's (6a - 4) divided by (7a - 5)...

OpenStudy (anonymous):

Oh 1 sec

OpenStudy (anonymous):

Alright either i am drawling a blank here or it's already in simplist terms due to the fact that there is no common factor. If you have the answer in the back of the book i will attempt to go step by step backwards to figure out what they want.

OpenStudy (anonymous):

maybe you just don't know how to do it lol np I'll try it out on my own I guess....I don't have the answer though. :S

OpenStudy (anonymous):

you can clear the fraction using an lcm and end up with -15a-9

OpenStudy (anonymous):

with nothing under it?

OpenStudy (anonymous):

It will clear the bottom if you do that. it would look something like ((7a-5)(6a-4)/(7a-5))-3(7a-5) the denomator will cancell and then you simplify

OpenStudy (anonymous):

thank you!

OpenStudy (anonymous):

i made a mistake on the signs so check them

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

its -15a + 11

OpenStudy (anonymous):

yea i did it in my head but just for aperance sake i would rewrite that to 11-15a just because it looks better and makes it easier when you are doing harder operations later in your math career
