These two expressions are not equivalent.
3[7-2(x+4)] simplifies to 21-6(x+4) which further simplifies to 21-6x-24 = -6x-3
The expression -6x+(-3) is already simplified and does not equal -6x-3.

The expression -6x+(-3) is already simplified and does not equal -6x-3.

I apologize for the mistake in my previous response. You are correct. Let's simplify the first expression again:
3[7-2(x+4)] = 3[7-2x-8] = 3[-2x-1] = -6x - 3
So, the two expressions -6x - 3 and -6x + (-3) are indeed equivalent. Thank you for pointing that out.
3[7-2(x+4)] = 3[7-2x-8] = 3[-2x-1] = -6x - 3
So, the two expressions -6x - 3 and -6x + (-3) are indeed equivalent. Thank you for pointing that out.
