To solve the equation "Five less than three-fourths of x is seven," we can write it mathematically as:
\[ \frac{3}{4}x - 5 = 7 \]
Now, let's solve for \( x \):
-
Add 5 to both sides: \[ \frac{3}{4}x = 12 \]
-
Multiply both sides by \( \frac{4}{3} \) (which is the same as dividing both sides by \( \frac{3}{4} \)): \[ x = 16 \]
Now, regarding the solution process, the last property of equality used in these steps is the Multiplication Property of Equality when we multiply both sides by \( \frac{4}{3} \) to isolate \( x \).
Thus, to justify the solution, we would use Multiplication Property of Equality as the last property of equality employed. However, since that option was not in the choices provided, if we focus on the last operation you perform in your calculation, it is the Addition Property of Equality when adding 5 to both sides to first isolate the term containing \( x \).
Therefore, the most appropriate response based on the last operation before we find \( x = 16 \) is:
Addition Property of Equality
