Question 802386
<font face="Times New Roman" size="+2">


You really only have one variable in the end.


First we know that *[tex \Large x\ +\ y\ +\ z\ =\ 110]


But we are given that *[tex \Large 4y\ =\ x\ \Rightarrow\ y\ =\ \frac{x}{4}] and *[tex \Large z\ =\ x\ +\ 2].  Now we can do a little substitution.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ \frac{x}{4}\ +\ x\ +\ 2\ =\ 110]


And then all you have to do is solve the single variable equation for *[tex \Large x].
