Which of these is not part of the solution process?

A. Dividing both sides by 12 to isolate the variable
B. Simplifying by combining variable terms
C. Adding 24 to both sides to isolate the variable term
D. Using the distributive property

Answer :

Sure! Let's go through the steps of solving the equation [tex]\(4(3x - 6) = 24\)[/tex] and identify which part is not included in the solution process.

1. Use the Distributive Property:
The equation starts with [tex]\(4(3x - 6)\)[/tex], which means you need to distribute the 4 to both terms inside the parentheses. This leads to:
[tex]\[
12x - 24 = 24
\][/tex]
So, using the distributive property is definitely a step in the process (this relates to choice D).

2. Identify the need for simplifying by combining variable terms:
In the equation [tex]\(12x - 24 = 24\)[/tex], there are no other variable terms to combine. We only have a single variable expression [tex]\(12x\)[/tex]. So, there is no step where you need to combine like terms (this relates to choice B).

3. Add or Subtract to Isolate the Variable Term:
To isolate the term with [tex]\(x\)[/tex], add 24 to both sides of the equation:
[tex]\[
12x - 24 + 24 = 24 + 24
\][/tex]
Simplifying the equation gives:
[tex]\[
12x = 48
\][/tex]
Adding 24 to both sides is definitely a valid step in the solution process (this relates to choice C).

4. Divide to Solve for the Variable:
Finally, divide both sides of the equation by 12 to find [tex]\(x\)[/tex]:
[tex]\[
\frac{12x}{12} = \frac{48}{12}
\][/tex]
Simplifying gives:
[tex]\[
x = 4
\][/tex]
Dividing both sides by 12 to isolate [tex]\(x\)[/tex] is a crucial step in the process (this relates to choice A).

Given this breakdown, the step that is NOT part of the solution process is:

B. Simplifying by combining variable terms

This is because there was no need to combine variable terms in the given steps.
