Yes. If equals are added to equals, then the results of the additions are equal.

To find the number that, when added to 2, equals 50, you can set up the equation: ( x + 2 = 50 ). By subtracting 2 from both sides, you get ( x = 48 ). Therefore, 48 plus 2 equals 50.
When equals are added to equals, you don't necessarily get wholes. But whatever you do get, they're equal.
