Simplifying the Expression

To simplify the expression 20 + 3(x - 15), we need to apply the distributive property and combine like terms. Let's break it down step by step:

1. Distribute the 3 to both terms inside the parentheses: - 3(x - 15) = 3 * x - 3 * 15 = 3x - 45

2. Combine the simplified terms: - 20 + 3x - 45 = 3x + 20 - 45 = 3x - 25

Therefore, the simplified expression is 3x - 25.
