You can put this solution on YOUR website!
graphing not practical for more than two variables
scale of graph can affect accuracy

a calculated solution (S or E) gives an exact answer; is usually faster; and requires less equipment

deciding on S or E usually depends on the type and value of the coefficients

E is usually easier for greater numbers of variables (more than two)
