\(\frac{1}{3} (12t - 15) \\ \\ \frac{1}{3} \times 12t \frac{1}{3} \times -15 \ / \ distribute \\ \\ 4t + \frac{1}{3} \times -15 \ / \ simplify \\ \\ 4t+ - \frac{1}{3} \times 15 \ / \ simplify \\ \\ 4t - \frac{15}{3} \ / \ simplify \\ \\ 4t - 5 \ / \ simplify \\ \\\)
Finally, we have reached our answer! The answer that expands the expression is 4t - 5.
