Answer :
To solve the equation [tex]\(\frac{z}{3} = 12\)[/tex], we want to isolate the variable [tex]\(z\)[/tex]. Here is a step-by-step solution:
1. Action: To isolate [tex]\(z\)[/tex], we need to eliminate the denominator in the fraction [tex]\(\frac{z}{3}\)[/tex].
- The most effective way to do that is by multiplying both sides of the equation by 3.
- Hence, the selected action is: B. Action: Multiply both sides by 3.
2. Property: The justification for multiplying both sides of the equation by the same number is based on a fundamental property of equality.
- This property states that if you multiply both sides of an equation by the same non-zero number, the two sides remain equal.
- Therefore, the property that justifies this action is: E. Property: Multiplication property of equality.
So, the correct selections are:
- Action: B. Action: Multiply both sides by 3.
- Property: E. Property: Multiplication property of equality.
Thus, the solution steps highlight:
- Multiplying both sides by 3 to isolate [tex]\(z\)[/tex].
- Justifying this action using the multiplication property of equality.
