Description: Subtraction and addition of equals. Almost but not exactly the same as pncan3i 8166 and pncan 8095, this order happens often when applying "operations to both sides" so create a theorem specifically for it. A deduction version of this is available as pncand 8201. (Contributed by David A. Wheeler, 11-Oct-2018.) |
