The correct answer is: 1

The equation can be rewritten as 3x = 16 - 7, which simplifies to 3x = 9. In order for this equation to have a solution, x must equal 3. Therefore, there is only one solution for this equation. Option A is incorrect because the equation does have a solution. Option C and D are incorrect because 3x + 7 = 16 does not have multiple solutions or an infinite number of solutions.
