Without the specific equation or steps provided, it is difficult to determine the exact missing reason. However, some common justifications used when solving equations include the following:
1. Addition or Subtraction Property of Equality: "Adding (or Subtracting) the same value to both sides of the equation preserves equality."
2. Multiplication or Division Property of Equality: "Multiplying (or Dividing) both sides of the equation by the same value preserves equality."
3. Distributive Property: "Distributing a value across parentheses does not change the expression's value."
4. Combining Like Terms: "Combining or simplifying like terms reduces the equation to a simpler form."
5. Solving for the Unknown: "Performing algebraic manipulations to isolate the unknown variable on one side of the equation."
6. Reflexive Property: "Numbers are equal to themselves."
7. Transitive Property: "If a = b and b = c, then a = c."
Identifying a missing reason would require analyzing the given equation and the steps followed, comparing them to the list of common justifications.
