solve for m by rewriting the equation (transposition) In the following equation how would I rewrite the equation to solve for $m$?
$$z=\frac{-4m-8+\sqrt{(4m+8)^2+4(4(mx+y-4m-4))}}{8}$$
when
$x=66$ and $y=22$ and $z=10$

the given expression is of the form 
$$z=\frac{-b+\sqrt{b^2-4ac}}{2a}$$
which can be reordered to form a quadratic in$z$.
$$az^2+bz+c=0$$
$a=4$,$b=4m+8$,$c=-(mx+y-4m-4)$
