B Correct answer
Explanation

x + 3(2x + 5) = -20 => x + 6x + 15 = -20 => 7x = -35 => x = -5.

AI explanation

To solve x + 3(2x + 5) = -20, we first distribute the 3 into the parentheses to get x + 6x + 15 = -20. Combining the x terms yields 7x + 15 = -20. Subtracting 15 from both sides gives 7x = -35, and dividing by 7 results in x = -5.
