+The first list returned in level 2 contains the value found for all variables, in this case ''X=2'' was the exact solution. The list in level 1 has the residuals of all equations. The residual is defined as the difference between the left and right sides of the equation. Notice that the residual is within the requested tolerance. Requesting a tighter tolerance would produce a result for ''X'' closer to ''2'' but at the expense of longer running time to find the solution.
