2017-03-15 11:49:41 -0500 | asked a question | How to simplify `solve` result ($r_i$ variables)? I want to solve a system of linear equations (more variables than equations): The result is shown like this: $\left[\left[a = -r_{39} + \frac{9}{2}, b = r_{39}, c = \left(-\frac{1}{2}\right)\right]\right]$ But I would like to have a simplified representation, i.e., where $r_{39}$ in the first equation is replaced by $b$. Alternatively, is there a way to reset the counter of the $r_i$ variables? Each time I evaluate the code above, the counter is incremented. |
