Yes, it has. Read Section 2.1 of the free book Computational Mathematics with SageMath (especially Tables 2.1 and 2.2).

Thank you. I was initially looking for "baby steps" transformations like AddSides ▪ SubtractSides ▪ MultiplySides ▪ DivideSides ▪ ApplySides, not realizing that I can simply: eq = 1/(x-1) == (x+1) and then eq *= x-1
