Explanation:
To divide the expression (15x - 12) by 3, you'll perform the division on each term of the expression separately. Here's the step-by-step process:
1. Divide the first term (15x) by 3:
(15x) / 3 = 5x
2. Divide the second term (-12) by 3:
(-12) / 3 = -4
So, (15x - 12) divided by 3 is:
5x - 4
