1. The problem asks for the solution set of an equation in $\mathbb{Q}$ (the set of rational numbers) with options a) 60 b) 150 c) 330 d) 120. However, the equation itself is not provided, so we cannot determine the correct answer without the equation. 2. The second problem asks which of the following equations has no solution in $\mathbb{Z}$ (the set of integers) with options a) 60 b) 40 c) 210 d) 130. Again, the equations are not provided, so we cannot determine which has no integer solution. Since the actual equations are missing, it is impossible to solve these problems or choose the correct answers. Please provide the equations or more details to proceed.
