What is the solution of the equation 3(x + 5) = 15?

The correct answer is: 5

To solve this equation, we need to isolate the variable (x) on one side of the equals sign. In this case, we can start by distributing the 3 to the parentheses by multiplying 3 to both terms inside the parentheses. This results in the equation 3x + 15 = 15. Next, we can subtract 15 from both sides to get 3x = 0. Finally, we can divide both sides by 3 to solve for x, giving us x = 0. Therefore, the correct solution for the equation is A (x = 0). The other options, B (x = 4), C (x = 3), and D (x = 10) are incorrect because they do not satisfy the original equation. Substituting these values into the original equation
