How would Veeky Forums solve this?

this is so trivial my first line would be the solution.

10/3 = 7/x
70/21 = 70/10x
x=2.1

[math] \displaystyle

\begin{cases}
z - 1 = 8 \\
z + 1 = 3
\end{cases}

\\ 2z = 11
\\ z = 5.5
[/math]

Actually fucking kill yourself and get off this board

...

you forgot 4. miltiplier

4* [(z-1)/3] = 8/(z+1)
