Let's say I have 3 equations:
s = y + d * r
r = b + d * q
q = x + d * m
Let's say d, q, and r are unknown.
Is it possible to solve for d?

replace r in the 1st equation by the above
s = y + d * ( b + d * ( x + d * m ) )
simplify:
s = y + d*b + d^2 * x + d^3 * m
thus:
d^3 * m + d^2 * x + d*b + y - s = 0
