Question

Proportion help. Please show work so I know how to do it.

Answer 1

cross multiply
(in other words: multiply both sides by 5 and 12)
to get 5(3y-8)=12y then solve for y...

Answer 2

Can you help me further, I am only good with basic proportions.

Answer 3

mmm? don't you know how to solve for y
from 5(3y-8)=12y

Answer 4

OK, hang on.

Answer 5

15y-40=12y, is that right

Answer 6

that is correct so far :)
now you can subtract 12y from both sides
and add 40 to both sides :)

Answer 7

3y=40

Answer 8

yup :)
then divide both sides by 3
(and I suggest you keep it as a fraction unless otherwise told)

Answer 9

y=13 1/3

Answer 10

yep :)

Answer 11

Cool thanks for your help.

Answer 12

Answer 13
