While simplifying an expression or solving an equation, every step of the work must have a reason allowing that step. Sometimes these reasons are properties. Even though a step may seem obvious, write out each step in full detail to help yourself see what's being used as a reason to justify the step. For instance, simplify: 12 + 2(x − 6) = 12 + 2x − 12 = 2x + 12 − 12 = 2x + (12 − 12) = 2x + 0 = 2x Each of the above steps has a reason for why I could do the step. them properties? If so, which ones? 1 Are any of
