The missing reason is the Distributive Property.
Solución
The missing step involves expanding the expression \( 2(x + 7) \). To go from \( 2(x + 7) + 3x = 12 \) to \( 2x + 14 + 3x = 12 \), you apply the **Distributive Property**, which states that \( a(b + c) = ab + ac \).
**Answer:**
E Distributive Property

The missing reason in the given equation is E Distributive Property. The first line shows an expression that involves distributing \(2\) into the sum \((x + 7)\), resulting in \(2x + 14\) before moving on to the next steps. To clarify the steps leading to \(5x + 14 = 12\), after applying the Distributive Property, you combine like terms to ultimately get your simplified expression.
