# Math Help - express y in terms of x

1. ## express y in terms of x

Q: if x = [6+6y]/(7+4y), express y in terms of x

i tried getting the y's all on one side..

(7+4y)x = 6(1+y)

i've been getting things like
7x/6 = 1+y-4xy

(6-7x)/(4x-6)

i just need to know the work how to get here

Good!

so you have 7x + 4xy = 6 + 6y

now how about putting all the terms with y in them on one side, and then factoring out the y ...
