Final answer:
An equation with one unique solution has different coefficients and different constants.
Step-by-step explanation:
An equation with one unique solution has the following properties:
- The coefficients are different: In an equation with one unique solution, the coefficients of the variables are distinct. For example, if we have the equation 3x + 2y = 5, the coefficients 3 and 2 are different.
- The constants are different: The constants in the equation, such as the right-hand side of the equation, are also distinct. In the equation 3x + 2y = 5, the constant 5 is different from other constants.
Based on these properties, options A and B are correct. Therefore, the correct answers are:
A. The coefficients are different
B. The constants are different
