Question 199345
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y(1-x)=z]


Multiply by *[tex \Large \frac{1}{y}]:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1-x = \frac{z}{y}]


Add -1 to both sides:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ -x = \frac{z}{y} - 1]


Multiply by -1, then apply the LCD of *[tex \Large y] on the right:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = 1 - \frac{z}{y} = \frac{y - z}{y}]


Remember to exclude zero as a possible value for *[tex \Large y], so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = \frac{y - z}{y}\ ,\ y \neq 0]


That's as far as you can go without some additional information.
