Since you described it as a proportion, I am guessing that this is what you meant: \(\dfrac{w+14}{4w+6}=\dfrac{3}{4}\)

The equation editor can help you to avoid confusion. So, to solve a proportion, you cross multiply.

i know how to cross multiply, but im confused with the w and the 4w
anonymous
  • anonymous
What did you get when you cross multiplied?

Then distribute.
anonymous
  • anonymous
so then you get.. 4w + 56 = 12w +18
anonymous
  • anonymous
Yes, and then solve for w.
anonymous
  • anonymous
So the answer is: w=4.5 thank you
anonymous
  • anonymous
REcheck your calculations....
anonymous
  • anonymous
I got w=4.75
anonymous
  • anonymous
oh i found my mistake i got 36/8 instead of 38/8

Great Job! You can always check your own answers by plugging your answer for x back into the original equation. \[\dfrac{4.75+14}{4w+6}=\dfrac{3}{4}\] \[\dfrac{4.75+14}{4(4.75)+6}=\dfrac{3}{4}\] \[\dfrac{18.75}{19+6}=\dfrac{3}{4}\] \[\dfrac{18.75}{25}=\dfrac{3}{4}\] \[0.75=0.75\]
