How would i go about solving this equaiton on mathematica (Xi -Ux)^2 + (Yi - Uy)^2 + (Zi - Uz) = (Ri - Cb) i = 1,2,3,4 where we need to find Ux, Uy, Uz, Cb tried a few things and they dont work. NSolve[ (Xi - U)^2 + (Yi - V)^2 + (Zi - W)^2 == (Ri - B)^2, {U, V, W, B}, { i = 1, 2, 3, 4} ] any ideas?
