Answer 1

Let's analyze the steps you've provided for solving the equation \(4(3x - 6) = 24\):

1. Starting Equation: \(4(3x - 6) = 24\)
2. Applying Distributive Property: \(12x - 24 = 24\)
3. Adding 24 to Both Sides: \(12x - 24 + 24 = 24 + 24\) → This simplifies to \(12x = 48\)
4. Dividing Both Sides by 12: \(x = 4\)

Now, let's identify which listed step is not part of the solution process:

• Using the distributive property: This step is used when expanding \(4(3x - 6)\) to \(12x - 24\).
• Adding 24 to both sides to isolate the variable term: This is part of the solution, as we add 24 to both sides to isolate \(12x\).
• Simplifying by combining variable terms: This step is not applicable in this process since we're not combining terms of different variables or constants in these steps. There are no variable terms to combine.
• Dividing both sides by 12 to isolate the variable: This step is used when solving for \(x = 4\).

The step that is not part of the solution process is Simplifying by combining variable terms.
