To simplify the expression and combine like terms, you need to follow a few steps:

Step 1: Distribute the -5 to the terms inside the parentheses.
-5(t-3) = -5 * t + (-5 * -3)

Step 2: Simplify the multiplication -5 * t = -5t and -5 * -3 = 15.
Therefore, the expression becomes -5t + 15 - 12.

Step 3: Combine like terms.
Simplifying further, -5t + 15 - 12 = -5t + 3.

So the simplified expression with like terms combined is -5t + 3.
