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?

Yes. replace q in the 2nd equation with the 3rd. r = b + d * ( x + d * m ) 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 1 equation, 1 unknown.
