Dividing by one on the second term is pointless: .75x/1 should be .75x
.08=.75x-.75x well... .75x-.75x is 0. Did you copy this right?
Yes i copied it correctly i also keep getting 0 but the answer sheet for the finance class it is for says x equals 0.0988 so i want to know how they got that answer...
I think we have.....
.08 = [(.75x)/(1- .75x)] subtract the expression from the right hand side to set the expression = 0 .....and using the on-site solver, we have......
$${\mathtt{0.08}}{\mathtt{\,-\,}}\left({\frac{{\mathtt{0.75}}{\mathtt{\,\times\,}}{\mathtt{x}}}{\left({\mathtt{1}}{\mathtt{\,-\,}}{\mathtt{0.75}}{\mathtt{\,\times\,}}{\mathtt{x}}\right)}}\right) = {\mathtt{0}} \Rightarrow {\mathtt{x}} = {\frac{{\mathtt{8}}}{{\mathtt{81}}}} \Rightarrow {\mathtt{x}} = {\mathtt{0.098\: \!765\: \!432\: \!098\: \!765\: \!4}}$$
or maybe we have
.08=0.75x/1-.75x
$${\mathtt{0.08}} = {\frac{{\mathtt{0.75}}{\mathtt{\,\times\,}}{\mathtt{x}}}{{\mathtt{1}}}}{\mathtt{\,-\,}}{\mathtt{0.75}}{\mathtt{\,\times\,}}{\mathtt{x}} \Rightarrow \left\{ \begin{array}{l}\end{array} \right\}$$
The empy parentheses indicate that this is an empty set. There are NO solutions.
I doubt that is correct, Melody...there is no purpose in writing the first fraction on the right side of the equation over 1......besides, the poster claims that the answer on his sheet was the same as I got......
