4(3x-6)=24

Question

4(3x-6)=24
12x-24=24
12x-24+25=24+24
12x=48
12x/12=48/12
x=4

Which of these is NOT part of the solution process?

Simplifying by combining variable terms
Adding 24 to both sides to isolate the variable term
Using the distributive property
Dividing both sides by 12 to isolate the variable

GPT-4o mini · Answer

The step "Adding 24 to both sides to isolate the variable term" is NOT part of the solution process.

Here's a brief breakdown of the other steps:

Using the distributive property: The first step simplifies $4 (3 x - 6)$ to $12 x - 24$ .
Simplifying by combining variable terms: The step where you have $12 x - 24 = 24$ and then rewrite it as $12 x = 48$ involves simplifying.
Dividing both sides by 12 to isolate the variable: This is present in the final step where you divide $12 x = 48$ by 12 to solve for $x$ .

The stated step of adding 24 to both sides did not occur in the solution process since the equation was already set up to isolate $12 x$ directly.
