Simplify: 8x - 3(2x + 4)

To simplify the expression 8x - 3(2x + 4), begin by distributing the -3 to both terms inside the parentheses.

Start with the term 3(2x), which simplifies to 6x, and then move to the term 3(4), which simplifies to 12. Since we have a negative outside the parentheses, this becomes -6x and -12 when we distribute:

[

8x - 3(2x + 4) = 8x - 6x - 12

]

Next, combine the like terms 8x and -6x:

[

8x - 6x = 2x

]

Putting it all together, we then have:

[

2x - 12

]

Thus, the simplified expression is 2x - 12. This aligns with the correct choice, which indicates that the answer is indeed accurate.
