9) If a = b, then a - c = b - c. This is the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ property of equality.
10) For all real numbers a, b, and c: if a=b, then a + c = b + c. This is the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ of Equality.

1) If a = b, then ac = bc. This is called the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ of equality. (2 words)
3) This is any and all value(s) of the variable(s) that satisfies an equation, inequality, system of equations, or system of inequalities.
5) This is the answer to a problem or an equation.
