Given the following mathematical expressions:
7. (8x – 3) + 12 = (8x – 3) + 12
8. If a = -3 and —3 = d, then a = d.
Then
7. These are simply equal. The left hand side and the right hand side are the same.
8. This represents transitivity. This is the property that when
if a = b, and b = c, thn a = c
