| May 27, 2021 at 11:51 | comment | added | Sergio Jorás | If i use both suggestions I've received, i.e, Format[r["+"]] = Subscript["r", "+"]; Solve[A (x - r["+"]) == B, r["+"]] Then I'll get exactly what I was looking for: $r_+= \frac{A x-B}{A}$. | |

Could also use r["+"].

Just call it rp. You could also use r₊ (U+208A) subscript plus sign, but I recommend against that. Also Subscript[r, "+"], but I don't like subscripts as they can cause problems - search for why.
